Please briefly explain what the PRBS (Pseudo Random Bit Streams) signal with UI (unit interval) means. (a) Construct a N=2^11 PRBS of a symmetric pulse with UI= Insec and rise/fall time = 1/10 of the pulse and plot its frequency spectrum using FFT (fast Fourier Transform) by numerical software, say MatLab. (b) Repeat (a) but the rise/fall time=1/4 of the pulse. (c) Repeat (a) by constructing a PRBS with N=2^15. (d) Can you predict or even prove the frequency spectrum when N tends to infinity.
