[Vikram Gogna]

r = randi([0 1], 1, 100);%a randi functin to generate a sequence of 100 random bits (0 or 1)

s = rectpulse(r,100);%rectangular pulse, where r is the row vector representing the random bits

time = [10^-9:10^9:10^-6];

figure(6);%plots graph 6

plot(time, s);%plots time against s

The rectpulse funciton is part of the Communications Toolbox. It must be liensed and installed.

There is a similar rectpuls function in the Signal Processing Toolbox.
