(a) Sketch each of the following signals in the frequency domain:
(i) A DSBSC signal with single-tone modulation. The carrier frequency is 10 MHz and the modulating frequency is 1 kHz. The average power is 5 W.
(ii) An SSBSC USB signal with two-tone modulation. The carrier frequency is 9.998 MHz and the modulating frequencies are 1 kHz and 3 kHz with equal amplitude for each. The average power is 5 W.
(b) Compare the two sketches. What do you notice about them
(c) How would a receiver distinguish between these signals
