Q. 6 In digital communications, half-cosine or raised-cosine pulses are sometimes used to shape a binary
waveform to reduce inter-symbol interference.
(a) Sketch and label the half-cosine pulse x(t)=Acos((\pi t)/(T))rect((t)/(T)) where A and T are positive
constants.
(b) Express the raised-cosine pulse, y(t), shown in Figure Q6.
