| + | Since the frequency analysis is made on the output signal using a basic envelope detector circuit, we are able to see both the message and carrier signal. In contrast to the applied input signal, where the carrier amplitude is larger than the message amplitude, on the spectrum analyzer plot we can notice that, in terms of magnitude, the message signal (100 Hz) is emphasized with respect to the carrier signal (see Marker table). | ||
