draw a block diagram of a simple amplitude modulation.explain briefly,how amplitude modulationis achieved.
Block diagram of Amplitude modulation:
- Initially, the modulating signal m(t) is added to the carrier signal c(t) to produce the signal x(t).
- The signal x(t) is allowed to pass through square law device to produce the output y(t).
- The output y(t) is given to band pass filter rejects dc and gives out the Amplitude modulated wave.
