Consider a random data pattern consisting of binary 1's and 0's, where the probability of obtaining either a binary 1 or a binary 0 is ½ Assume that these data are encoded into a polar-type waveform such that the pulse shape of each bit is given by
where Tb is the time needed to send one bit.
(a) Sketch a typical example of this waveform.
(b) Find the expression for the PSD of this waveform and sketch it.
(c) What is the spectral efficiency of this type of binary signal?
