Answer Posted / harimohan k. bhagwane
pre emphasis is a process which is used in transmitter side
to boosting the amplitude of higher modulating signal
before modulator.IF we used it after the modulator than
carrier &modulator signal will mixed and it is difficult to
verify which one is the modulating signal.
de emphasis is process which is used in receiver side
to reduced the signal & get their original signal.But it is
used after demodulator ckt.
