WebGenerate the DSB-SC signal and measure modulation depth 3. Use coherent detection to demodulate a DSB-SC signal 1.0 Introduction Like DSB-AM, in DSB-SC the message signal is used to electrically vary the amplitude of a pure sinewave called the carrier. Figure 1 shows a simple message signal and an unmodulated carrier. It also shows the result of … WebSketch the spectral density of the resulting DSB-SC waveform, identifying the upper and lower sidebands, for each of the following cases a) f (t) cos 100m; b) Fl cos (/200)]/2 …
