Please briefly explain what the PRBS (Pseudo Random Bit Streams) signal with UI (unit interval) means. (a) 

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.
