draw a block diagram of a simple amplitude modulation.explain briefly,how amplitude modulationis achieved.

Block diagram of Amplitude modulation:



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.
