7.2-2 (a) A random binary data sequence 100110 is transmitted using a Manchester (split-phase) line code with the pulse p(t) shown in Fig. 7.6a. Sketch the waveform y(t). (b) Derive S, (w), the PSD of a Manchester (split-phase) signal in part (a) assuming 1 and 0 equally likely. Roughly sketch this PSD and find its bandwidth.
