The terms ‘AM’ and ‘FM’ refer to forms of signal modulation — a method at the heart of modern long-distance communications. Signal modulation simplifies the technologies required to send ...
FM radio works the same way that AM radio works. The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to ...
Compared to the simple diode needed to demodulate AM radio signals ... fixed-width square wave pulse at a set point in the received FM signal’s waveform, usually at the zero-crossing point.
Below is a list of all the BBC's radio services that are available on FM and AM. We have listed the frequency ranges, if you want to know the exact frequency for your location then use our ...
That’s good enough for AM radio, anyway, but you’ll need to ... cousins because the circuitry necessary to demodulate an FM signal needs a frequency-to-voltage conversion that isn’t ...
Some can also combine television and FM radio signals. If you are experiencing pixellation or picture break up, it may be that your signal is too strong as this often presents itself similarly to ...
