How does a stereo FM radio receiver work?
FM stereo radio stations broadcast in stereophonic sound (stereo), transmitting two sound channels representing left and right microphones. A stereo receiver contains the additional circuits and parallel signal paths to reproduce the two separate channels.
How does a tuned radio receiver selectivity work?
Tuned Radio Frequency, TRF, receiver : As the name implies this type of receiver relies on the filters in the RF sections of the radio to provide the selectivity. As these are variable and often at a relatively high frequency, selectivity is not as good as that provided by the superheterodyne and direct conversion receivers.
How to design a simple digital radio receiver?
With many new advances in data converter and radio technology, complex receiver design has been greatly simplified. This paper attempts to explain how to calculate sensitivity and selectivity of such a receiver.
Can a digital radio receiver be reprogrammed?
Furthermore, since the core of the digital processor is a digital signal processor (DSP), this allows many aspects of the entire radio receiver itself be controlled through software. As such, these DSPs can be reprogrammed with upgrades or new features based on customer segmentation, all using the same hardware.
How can I get Satellite Radio on my stereo?
A lot of satellite radio adapter kits – especially the cheap ones – use something called an FM modulator to get the satellite radio signal from the receiver to your stereo’s head unit. An FM modulator is a miniature FM radio station. It broadcasts satellite radio over a short-range.
How can I add FM radio to my factory stereo?
The best FM modulators will require you to remove your factory stereo, unplug the factory antenna, and then plug it into your modulator. The modulator then has a wire to plug into the factory stereo. We call this a piggyback style FM modulator.
How can I get FM radio on my car?
High pitched whines, static, popping noises – these are all pretty common. The best FM modulators will require you to remove your factory stereo, unplug the factory antenna, and then plug it into your modulator. The modulator then has a wire to plug into the factory stereo.
Can a satellite radio be mounted on the dash?
You still need to mount some sort of satellite unit on the dash of your car You need to run two sets of wires – one for power and one for signal – from the satellite box on the dash to the AUX input and (most often) your cigarette lighter You have to change satellite radio stations using the dash mounted receiver box
