I can create an rectangular pulse with code
b1 = 5;
a1 = 5;
x = -10:0.01:10;
% a pulse function
f = @(xi,a,b) a*rectpuls(xi,b);
% plot to
plot(x,f(x,a1,b1),'b--');
title(['Rectangular Pulse']);
xlabel('Time');
ylabel('Amplitude');
I now want to move this pulse, to start from x = -2 and end at x=+3, i.e. not have it centred around zero?
Any idea how to make it so?

captain, how about
plot(x,f(x-0.5,a1,b1),'b--');

Did not think about moving the x vector. Many thanks!

Hi Mischa Kimm and Captain Mariah,
Please I need help with the fft of that rectangular pulse as well as its power spectral density
How do I also extract the bandwidth from the PSD?
Kindly assist, any hints/clues will be appreciated
Thanks
Elijah
