ReplyDeleteoption d....for example: envelope detector....it first extracts the envelope of the received signal(equivalent to rectification and discarding carrier)....after the envelope is extracted,it is passed through a low pass filter to remove dc component and to smooth the signal(equivalent to providing audio signal)...
