the input m(t) is replaced by the received signal s(t), the cosine and sine amplitudes are set to 1, and the plus sign is chosen at the output adder. In practice, the demodulator would be preceded by an bandpass filter that passes the signal components and rejects out-of-band noise. Need for a Pilot Tone These two demodulators assume that the ...

Chapter 5 Amplitude Modulation AM was the first widespread technique used in commercial radio broadcasting. An AM signal has the mathematical form s(t) = Ac[1+kam(t)]cosωct where • m(t) is the basebandmessage. • c(t) = Ac cosωct is called the carrierwave. • The carrier frequency, fc, should be larger than the highest spectral component ...
