Draw a block diagram of a detector for AM signal and show, using necessary processes and the waveforms, how the original message signal is detected from the input AB wave
Original message is detected from AB wave using Demodulation, In which
original information-bearing signal from a modulated carrier wave is extracted. A demodulator is an electronic circuit that is used to recover
the information content from the modulated carrier wave. There are many
types of modulation so there are many types of demodulators. The
signal output from a demodulator may represent sound, images or binary data
These terms are traditionally used in connection with radio receivers,
but many other systems use many kinds of demodulators. For example, in a modem, which is a contraction
of the terms modulator/demodulator, a demodulator is used to extract a
serial digital data stream from a carrier signal which
is used to carry it through a telephonic line, coxial cable or optical fibre.
