6.2-3 For baseband modulation, each bit duration is Th. Consider a pulse shape P1(t)=Δ(1/2Tb)

(a) For a random binary data sequence 01001010110, sketch the polar signal waveform y(t).

(b) Find PSDs for the polar, on-off, and bipolar signaling.

(c) Sketch the resulting PSDs and compare their effective bandwidths.
