For a DSB-SC carier signal, the carrier is A. cos m,t, and the carrier frequency is much greater than the message signal bandwidth. (a) Sketch the modulated signal waveform if (i) the message signal is 0.54, cos omt and (ii) the message signal is the triangular waveform of Figure 3.3 with Mp = 0.5A.. (b) Sketch the modulated signal if (i) the %3D message signal is 24. cos omt and (ii) the message signal is the triangular waveform of Figure 3.3 with mp = 24.. Figure 3.3. Modulating signal for Practice problem 3.1 2T -mp
