Question

In a phase modulation (PM) system a message signal (?) is given as in Fig. 1.a. The frequency
of the carrier signal ?? = 100 kHz , the amplitude of the carrier signal is given as A? =1 Volt and the
frequency deviation ∆? = [6] kHz. If the PM signal is demodulated as in Fig. 1.b. Sketch the
signals at points c, d, e and f. (HPF in the figure only blocks DC component. In your sketches, please
specify amplitudes and frequencies)
