Tutorial Sheet # 2 1. Sketch the time variation and frequency spectrum of an RF signal with 75 % Amplitude Modulation. Show several cycles of the modulated wave. Make the modulation frequency 1/10 of the carrier frequency. The unmodulated carrier has peak amplitude of 1.0V. In an amplitude modulation system‚ the message signal is given by Fig. and the carrier frequency is 1 KHz. The modulator output is SAM (t) = 2(b + 0.5m (t)) cos ωc t. 2. a. Determine the average message power. b. If b =
