A modulation of Binary Phase Shift Keying (BFSK) can accomplished by simply multiplying the original signal r(t) with the carrier signal. Assume that input bit stream is r(t)=[1001] and carrier signal is c(t)= cos wt. With a suitable block diagram and constellation diagram, analyze the concepts of the flow of signal from input r(t) until the yield of output s(t) and determine the type of signaling produced by BPSK modulation.

Frequency-shift keying (FSK) and Phase-shift keying (PSK) Two other modulation schemes are the phase-shift keying (PSK) and the frequency-shift keying (FSK). These are illustrated in Figure 8 b and c respectively. In phase-shift keying the carrier signal changes phase by a radians when the digital signal changes values. In frequency-shift keying a 0 is transmitted at a different carrier frequency...
