Distinguish between Angle modulation and Amplitude
modulation.
Answer Posted / tariq
Angle Modulation is modulation in which the angle of a
sine-wave carrier is varied by a modulating wave. Frequency
Modulation (FM) and Phase Modulation (PM) are two types of
angle modulation. In frequency modulation the modulating
signal causes the carrier frequency to vary. T. In phase
modulation the phase of the carrier is controlled by the
modulating waveform.
In amplitude modulation, the amplitude of the carrier
signal is varied according to the modulating signal a and
other characteristics of signal(frequncy and phase) are
kept constant
