WebLet us consider a modulating signal m(t), which is given by, m(t) = A m cos ω m t. and the carrier signal c(t), given by the expression. c(t) = A c cos ω c t. Now, when the amplitude of the carrier is changed according to the message signal, an amplitude modulated wave is generated which is given by. y(t) = A 0 cos ω c t. Here, A 0 = A c + m(t) WebDetection. Detection is the process of retrieving the original signal from the modulated form. Consider the above diagram showing ‘demodulation’ of a received signal. The original frequency of the signal is let us say ‘ωc’ corresponding to the signal ‘c’ in the diagram. This signal is modulated using a carrier signal having a ...
