Rectangular Pulse MATLAB implementation

Hey Guys just asking how you would implement this function into matlab. I'm quite unfamiliar with the Rectangular pulse function and I am wondering how I would represent this function. My key issues are how to implement the Base 5000 values and the (f+ or f- 6000) system. This is a Fourier transform so don't worry about f too much.

Thanks a lot for your help!

What does the base 5000 indicate?

Answer 1

[MULI]

Hi @Aidan Kelly,

From your attached image I understand that the equation represents two rectangular pulses (each of width 5000 Hz), centered at ±6000 Hz, and scaled by 3/2. This can be implemented using "rectpuls" function from the Signal Processing Toolbox.

f = -20000:1:20000;
s_rov = (3/2) * (rectpuls((f - 6000)/5000) + rectpuls((f + 6000)/5000));

The "rectpuls" function generates a pulse of width 1, centered at 0, so scaling is needed.

For more information on this function you can refer to this MathWorks documentation link:
