Assume that the modulator and demodulator for the FH-SS system of Fig. 5–42 are of the FSK type.
(a) Find a mathematical expression for the FSK-FH-SS signal s(t) at the transmitter output.
(b) Using your result for s(t) from part (a) as the receiver input in Fig. 5–42b [i.e., r(t) = s(t)], show that the output of the receiver bandpass filter is an FSK signal.
