How receiver detect that which is information signal and which is carrier signal and how it seprat..

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
