How can I find the complex fourier series and plot the the fourier series of piecewise function ?

Hello guys,

I read the rules about asFking about home work help so I will not show my full code

so this is my tesk:

we have this signal X(T) with a period of T= 4

and the first think I was nedded to do is to plot it betwwen [-10 10]

so i used syms t and hendele function and with a for loop i created this :

fff

and now i stuck becuse i need to make complex fourier series on this and this is really hard becouse it is not simple function

can you please help ?

I need to write a function that will find ck with the foemula above and proof nomericly what I calculeted and also plot the series on matlab for N=10 and stuff like this but i stil dont know how to do this :(

Hi,

I understand that you need to find and plot the Fourier series of a piecewise function.

Your issue is somewhat, if not entirely, similar to the issue resolved in the following MATLAB Answer:

You can refer to its answer to understand how we can calculate and plot Fourier series of a piecewise function.

I hope this resolves your issue.
