Let the modulating signal m(t) be a sinusoid of the form m(t) = cos 2πfmt, fm << fc, and let the carrier signal be cos(2πfct + φc).
(a) Determine the conventional AM signal, its upper and lower sidebands, and its spectrum if the modulation index is α.
(b) Determine the DSB SC AM signal, its upper and lower sidebands, and its spectrum for m(t) = α cos 2πfmt, fm << fc.
(c) Determine the two possible SSB AM signals and their spectra.
