How do radios separate radio waves?

The radio converts EM waves through the Transmitter/Receiver. This works because if you pass a magnet over a wire it creates a small electric charge, all EM frequencies do the same so the T/R...

Sound. More information After a modulated carrier signal has been received through the radio's aerial, the radio de-modulates it to release the live sound as picked-up from microphones in the radio...

Radio doesn't do us any good as a means of communication unless we have a way to make the bare, naked radio wave carry information somehow. In order to do that, we change some characteristic of the...

Both AM and FM radio waves use a continuous carrier wave. With AM the frequency is constant and amplitude of the wave is varied to carry the transmitted information (modulation). With FM the...
