a binary signal is filtered with r = 1 and then modulated onto a carrier for transmission at 9600bps
a) what is the bandwidth requirements if the modulation is ASK?
b) BFSK with f1 = 100khz and f2 = 120khz (FSK bandwidth = B = 2fd + (1+r)R
c) using the same centre frequency as in b) , choose two new frequencies with minimum frequency separation

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.
