The message signal for a phase modulation (PM) is given in Figure 1. a as shown. The carrier signal has an amplitude of Ac = 1 Volt and a frequency of fc = 100 kHz, with a frequency deviation of Δf = [15] kHz. Since the resulting PM signal is demodulated as shown in Figure 1. b, please draw the signals formed at points c, d, e, and f. (The YGF in the figure only suppresses the DC component. Please indicate the amplitude and frequency information in the figures you draw. ) Figure 1. a Figure 1. b
