Define Pam And Write Down Its Drawbacks?

Answer»

PULSE Amplitude Modulation is the process by which the amplitude of the regularly spaced PULSES varies according to the the amplitude of the modulating SIGNAL.

The drawbacks are:

  • Since the amplitude of the pulses varies therefore the peak POWER of the modulating s/g is much greater.
  • The bandwidth required for TRANSMITTING is greater since the amplitude varies.
