Answer Posted / starry
angle modulation :it is the process of varying angle of a
signal ( carrier signal) with respect to instaneous
amplitude of another signal known as message signal.
***
angle in the sense either frequency or phase.
amplitude modulation :it is the process of varying
amplitude of a signal ( carrier signal which is with zero
reference ) with respect to instaneous amplitude of another
signal known as message signal
noise :
unnecessary things occured in the process of modulation
that may be either amplitude or frequency or phase.
