Delivering High-performance Car Radio Designs At Low Cost With Digital Low-if Cmos Amfm Automotive

admin  Automotive  , , ,

High-growth economies such as Brazil, Indonesia, India and China have an emerging middle class and rapidly growing automotive markets. The vehicle retail price in these markets must be relatively low, putting cost pressure on components in these vehicles. Additionally, automotive markets in developed economies such as the United States, European nations and Japan are also seeing an increased demand for cost-sensitive solutions after the global financial crisis that began in 2008.

Traditional technologies used in automotive AM/FM tuners are typically BiCMOS tuners with a 10.7 MHz IF tuner architecture. This technology/architecture delivers on radio reception performance, but the process and architecture are cost prohibitive for mixed-signal architectures where RF circuits are integrated with digital processing engines such as DSPs and microcontrollers in a monolithic circuit to deliver fully processed audio outputs.

Digital low-IF CMOS AM/FM receivers very much fit the bill due to the much lower cost points of CMOS foundries and the use of a digital low-IF tuner architecture. Digital low-IF AM/FM receivers have been in use in the handset and portable media player markets for a number of years.

RF Dynamic Range
In crowded FM spectrums that are very common in urban settings, the abundance of radio stations can overwhelm the radio receiver tuned to a desired station whose signal strength is relatively weak. The most severe and common non-linear distortion resulting from strong interferers is third order inter-modulation (IMD3) distortion resulting from two strong close-in blockers that show up on-channel on a weak desired station tuned to.

In many applications an external tracking filter is used on the front end of the receiver to attenuate the blockers. This technique, however, is costly in terms of components and PCB real estate.To minimize IMD3 distortion products, the dynamic range of the receiver front end must be adequate.

Selectivity and Dynamic Bandwidth Control
Selectivity refers to a tuner’s ability to receive a weak station in the presence of stronger stations at small frequency offsets. This is especially important for receivers in crowded FM spectrums in urban environments. An important performance requirement, especially for European markets where the channel spacing is 100 kHz for FM broadcast, is adjacent channel selectivity, which refers to suppression of signals 100kHz away from the tuned frequency and which is usually no better than 30dB in many tuners found in the low-cost category.

While 30 dB selectivity performance may be adequate for many field conditions, there are many situations in the world in which a listener is tuned to a station broadcast from a distant location while driving past towers broadcasting multiple stations in the local region. In this scenario, much higher selectivity is required.

Sensitivity
Sensitivity refers to a tuners ability to pull in weak stations. If you live in a rural area away from the transmitters of most radio stations, the sensitivity of a tuner will be of great importance. With current car radios, the performance requirements are typically microvolt level sensitivity, allowing the car radio to pull in an extremely weak signal and extending its ability to tune into a station dozens of miles away.

Alternative frequency (AF) Check
In Europe, alternative frequency (AF) technology is an optimal choice that allows the car radio tuner to tune to a different frequency that provides the same station when the first signal becomes too weak when moving out of range. This technology is often used in European car radio systems, enabled by radio data system (RDS) technology where the AF list is transmitted via RDS data.

In summary, continuing cost pressures in the global automotive market are driving the development and deployment of highly integrated and innovative CMOS radio receiver IC solutions that will provide significant cost savings in transitioning from traditional architectures and analog-centric semiconductor processes typically employed for car radio tuners.

How Automotive Windshields Are Repaired

admin  Automotive

Broken automotive windshields are no laughing matter. The term broken can be used lightly in some situations, and not so lightly in others. A broken windshield is considered to be a windshield that has a chip, crack, or spider web appearing crack within it. Damaged automotive glass can be a serious issue. If you do not get the problem rectified immediately, it can make it impossible for you to be able to operate your vehicle.

Even tiny dings that appear on this area of your vehicle can turn into larger problems down the road. When these small dings start to grow, they can block out your vision, which makes operating your vehicle a hazard in itself. Windshield replacement can help you fix a broken car windshield. Replacements are not the only solution to your problem though.

Smaller flaws that have not grown to be bigger messes can be rectified with simple repairs. These repairs can help you restore the strength of your vehicles glass, and help you avoid having to have this entire portion of your vehicle replaced down the line. Understanding the way that these repair services are carried out, will give you a general idea of what you can expect, if your vehicles windshield ever becomes damaged.

One of the first things that a repair service will do before fixing the problem is perform an evaluation of the damage. The repair personnel will examine the simple chip or crack. They will determine the size of the crack, and also look at the depth of it as well. Location is also a major factor that has to be considered when fixing this portion of your vehicle.

A lot of smaller flaws that are made to automotive windshields can be fixed by applying a resin to the surface of the chip or crack, and allowing it to dry. Be aware, that the only time that a repair service will use a resin to fix a chip or a crack that appears along your vehicles windshield is if the bottom layer of your glass has not been damaged.

Most of the modern day windshields that are placed on cars are made up of two glass layers. In between these two layers, there is a laminated rubber membrane. Resin repair services will only be able to fix damages that do not surpass the rubber membrane layer of your windshield. In the event that both layers of the part are damaged, you will need to look into having this entire portion of your vehicle replaced, as opposed to just having to patched up a little bit.

Some cracks that appear along the outer perimeter of your vehicles windshield can also be difficult to correct with a simple resin layer repair. Therefore, before hiring a repair service to fix your issue, it is important that you evaluate the state of the damage first. Be aware, that most companies that offer repairs will offer full replacements of the product as well. However, there are some companies that offer repairs that do not offer replacement services. Therefore, it is up to you to determine what type of service you believe you may require.

After you have personally determined that the only thing that needs to be done to your windshield is a simple repair, the repair process is fairly easy. A typical repair job will take about thirty minutes to complete. Using a special type of sunlight cured resin; the repair person will inject the epoxy onto the area that is cracked.

They will use special tools during the application process, in order to ensure that the repair is going to suffice. The tools that are used are designed to fix cracks and chips that do not pass the first layer of glass on the part. After the resin is applied to the area, you will need to wait a few minutes for the substance to dry, before using your vehicle.

The good thing about the resin is it dries clear. This will make it appear like there was never anything wrong with the product. The clear drying resin will match the remaining portion of your vehicles windshield. The sunlight is what is used to dry the resin, after it has been applied. Therefore, you will not have to do anything additional after having a repair service performed on this area of your vehicle. There are not a lot of people that realize how significant automotive windshields are, until they are forced to repair this portion of their vehicles. A broken windshield will make you a hazard on the road, aside from that it will ruin the beauty of your vehicle.

How To Go About With A Diy Battery Desulfator Project

admin  Automotive  

If you’ve had your car for a relatively long time then you’re probably aware that car batteries last only for a period of about two to four years. But, did you also know that you don’t have to throw your car battery away as soon as it goes dead? What if we tell you that there’s a way for you to bring your battery back to life and get it working as if it was brand new? Wouldn’t it be nice if you could extend your battery’s life and not have to buy a new one for at least a few more years?

The good thing is that this is actually possible. Most car batteries can actually be reconditioned and made to work like new with a device called a battery desulfator.

What causes a battery to go dead in the first place?
It is important to learn the answer to this question before you can even begin to understand how a battery desulfator works. A battery’s lead plates normally come into contact with the sulphuric acid content of its electrolytes whenever the battery goes into a discharge. The resulting compound is known as lead sulphate. When the battery is recharged, the lead sulphate is once again broken down into separate lead and sulphur components. However, some of the lead sulphate crystallizes on the battery’s lead plates and does not get broken down. Over time, the crystallized sulphate accumulates until it covers a majority of the lead plates, leaving no room for it to react with the electrolytes and create an electrical charge. This is when we say that a battery is -dead.-

A battery desulfator brings your battery back to life and gets it back to working like new by breaking down the crystallized lead sulphate and clearing up the battery’s lead plates. This way, the lead on the plates can react with the electrolytes properly and your battery can once again hold an electrical charge. Battery desulfation and reconditioning can be done at an automotive shop for a fee, but you can save on the cost by reconditioning the battery yourself. Of course, you’ll have to have your own desulfator for this purpose.

Where to get a battery desulfator
Desulfators can be bought from any automotive store, but why spend that much money when you can actually make the device for much less? The materials needed in making your own battery desulfator can be easily found in your junk box or somewhere around your house. And even if you don’t have them handy, these materials can be bought at very low prices from your local hardware or electronics shop. As for the process itself, you can get some good schematic diagrams and instructions online.

Aside from DIY battery desulfator guides and diagrams, the internet is also rife with reconditioning guides, so the process of both making your own desulfator and reconditioning your own battery is definitely easy enough for you to undertake. As soon as you have completed your desulfator project, you can practice reconditioning an old battery and then perform the process on your existing battery in order to prolong its lifespan.

Purchase Original Automotive Parts Every Time

admin  Automotive  ,

The automotive industry in India is the sixth largest passenger market in the world. In the coming future, it is going to see a very large growth. According to an estimation done by the Society of Indian Automobile Manufacturers the annual sales are expected to increase by 4 million by the year 2015. It has already overtaken Brazil in the manufacturing of cars. Entry of foreign market players is also expected to rise in the demand. The current generation of cars combines luxury that provides all the amenities of comfort.
The automotive parts are quite important in any vehicle. They include fasteners, springs, wheel bolts, nuts and many more. It is necessary to keep them in good condition always so that it gives good performance and sustains for a long period. The automotive parts of a vehicle vary from one to another. Most of the time, we purchase the spare parts of an automobile without having sufficient knowledge about these parts. Sometimes, the automotive parts manufacturers might provide a loose part to the customers. In the later period it becomes very difficult as the customer faces numerous problems.
The most important part in any vehicles is its brakes. If they fail to work properly then it can result in dangerous consequences that are an accident can take place. You should always change your brake oil within a period of two years. Changing the brake oil frequently, not only helps to keep the brake in shape but you can also use it for a long period of time. Experts also recommend that brakes of a car should be changed after every 40000 miles. Moreover, second hand brakes should never be purchased at all. One should always purchase new brakes whenever that has been used for a prolonged period of time. It is not necessary that you should always purchase the branded parts but whatever parts you purchase should be durable. You might even take a person who has a good knowledge about automobiles while you go to purchase the parts.
Taking extra precaution by the car owner can also help to reduce the damage done on the brakes. For instance: it is better not to take out the car in rainy season or during snow fall until and unless it is an emergency. The reason for this is that the dust and the water on the road often stick to the brakes and thereby making them less flexible. If we apply this simple precaution then certainly we do not have to visit the service centre or the repair shop frequently.
Like the automotive parts in a vehicle, the hardware of a computer should also be checked properly before purchasing them. While purchasing a second hand computer it is necessary that the hard disk should be checked properly. You should be first of all sure that all the parts are working properly and should then make the final purchasing decision. You can check the logo of the manufacturers of hardware parts before purchasing the computer parts.

Towell Auto Centre To Launch Mazda Cx-9 In Oman

admin  Automotive  , , ,

The Mazda Motor Corp. will be increasing its Zoom-Zoom family presence in Oman. This goal will be backed by Towell Auto Centre by launching the all-new Mazda CX-9.

“This is the first time the Mazda family is bringing an SUV to Oman, so there is much excitement among the fans of Mazda. We can assure our customers that the eager wait for the outstanding vehicle will be well worth it and we are sure to give the sultanate’s SUV market a new definition,” said S Kasthurirengan, General Manager, Towell Auto Centre.

The CX-9, based on the stretched Mazda6 platform, is a seven-seat sports crossover sport utility built alongside the small CX-7. The SUV, manufactured at the Ujina 1 plant of the automaker in Hiroshima Prefecture, Japan, made its official global debut at last years New York International Auto Show.

The all-new CX-9 features the 3.5 L Ford “Cyclone” V6 engine dubbed as the “MZI” in Mazda guise. The 2008 version of the SUV uses a 3.7 liter V6 engine. According to the Japanese automaker, the new engine will produce 273 horsepower and 270 pound-feet of torque. Additionally, the CX-9 will use an Aisin sourced six-speed automatic transmission with a console-mounted shifter which can be likened to the complex Mercedes-Benz gate.

The CX-9 flaunts more muscular stance and an angular nose. Its sedan-like honeycomb grille adds to its atypical appeal and makes the Mazda CX-9 stand out from the rest in its category. 20-inch alloy wheels come in this machine along with features like high-intensity-discharge (HID) headlights, said AME Info.

On board this stunner is comfort and roominess in splendid abundance, AME Info continued. The three-row sport utility vehicle has front bucket seats and a 60/40 split second row, with a backrest that can recline or fold flat. The third row splits 50/50 and features easy adjustments to make more room for leg space and cargo. Bose stereo with surround sound, keyless entry, power windows and cruise control are standard features on a Mazda CX-9. Add to this the refined chrome accents and dimmed windows for the final touches of a pure feel of opulence.

To bolster the safety features of the SUV, Mazdas pool of engineers have incorporated a bunch of standard equipment that includes the Dynamic Stability Control, Traction Control, Roll Stability Control, front side impact airbags and 3 row side Air Curtains. The CX-9 will offer options such as a Handsfree Bluetooth phone link, DVD navigation system, Backup Camera, and a rear entertainment system with the Bose 5.1 surround sound.

The Mazda CX-9s standard safety features also cover an all disc antilock brakes, side impact air bags, three-row side air curtains and an Electronic Stability System (ESS) with rollover mitigation technology, and traction control systems.

Crammed with superb auto features and refined with amenities and finesse like no other in its class, the CX-9 SUV promises to bring an elating dose of Zoom-Zoom to Oman. What is more, the sport utility also gives a wider leeway for customization. Moreover, Mazda aftermarket parts will serve their purpose well.

Separately, Mazda will be offering the Summer Stunner to give aficionados new hope. The ongoing offer entitles a participant to free registration, free five-year unlimited warranty on mileage, free 24-hours road assistance and gift shopping vouchers.

The main aim of this special promotion was to tailor-make deals for customers according to their individual needs and specifications. We are very glad that we have successfully been able to offer flexible deals to numerous car enthusiasts and bring smiles on the faces of those like Irene, whose vehicles have suffered losses due to the effects of the recent cyclone, said Annurag Chawla, the Mazda brand manager.
