Let a random process consist of a sequence of pulses with the following properties: ( i) the pulses are rectangular of equal duration, Δ( with no “ dead” space in between pulses), ( ii) the pulse amplitudes are equally likely to be ±, ( iii) all pulses amplitudes are statistically independent, and ( iv) the various members of the ensemble are not synchronized.
(a) Find the mean function, µX (t).
(b) Find the autocorrelation function, RX, X (t1, t2).
(c) Is this process WSS?
