Answer / rakesh

since the work of demodulator is to demodulate high frequency carrier signal,so in its recovery circuit it employs a circuit which does not allow high frequency signals to pass , but passes the low frequency signal.
where the high frequency is carrier signal & information being the lower frequency .( According to the definition of Modulation)

Answer / farhan

the demodulation is to ckeck tha singal through phase &
frequecey of the singal and the low pass filter reject the
high frequncy singal

Answer / r.jayashankar

Demodulator at the receiver will separate carrier and
message signal..

Answer / parth

There are different technique employed for the detection of the modulated wave so for AM wave or other the envelope detector is used that separate the carrier from the modulating signal by using diode
