Q: How exactly does an FM transmitter work?

A: Re: How exactly does an Fm transmitter work? FM (frequency modulation) simply means the transmitter output frequency is proportional to the amplitude of the input (modulating) signal. The larger or louder the input signal the higher the transmitter frequency. The amplitude of the transmitted signal is constant – only its frequency changes.

Q: What is the difference between FM and AM transmitter?

A: AM broadcasting is simpler than FM but the difference in complexity and price are very marginal at present. AM is more prone to signal distortion and degradation compared to FM. FM doesn’t degrade linearly with distance. AM usually broadcasts in mono which makes it sufficient for talk radio. FM can transmit in stereo making it ideal for music.

Q: What are the best frequencies for an FM transmitter?

A: The lowest and least-used FM frequency is 87.8. However, most car radios can’t go lower than 88.1. If you are looking for an unused FM frequency, most unused frequencies can be found in the low or high end of the FM range of your radio. These tend to be the best FM frequencies to use with your FM transmitter.
