The two signal waveforms for binary FSK signal transmission with discontinuous phase are
where ?f = 1/T c, and θ0 and θ1 are independent uniformly distributed random variables on the interval (0, 2π). The signals s0(t) and s1(t) are equally probable.
1. Determine the power spectral density of the FSK signal.
2. Show that the power spectral density decays as 1/f2 for f c.
