Amplitude Modulation (AM)

The modulation of a signal is essential if one wishes to transmit it over long distances.  Modulation  also provides a means for simultaneous transmission of several signals, using the same transmission channel (Hertzian, cable ...).

Amplitude Modulation (AM) is the simplest and the oldest of modulation methods, primarily because the stage of demodulation, at the receiver, is simple to carry out.  A modulator, followed by a filter, is sufficient to obtain an amplitude modulated signal, but it should be pointed out that this type of modulation generates numerous distortions and so frequency modulation (FM)   is now the preferred modulation method.
