Creating a rectangular pulse

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

xlabel('Time');

ylabel('Amplitude');
