hello all,

I have a one period square wave on the interval[0,2] defined as:

y(t)= 1, 0<=t<1

y(t)= 0, 1<=t<2

I need to find the fourier series coefficients,ck, with

k=-10,-9,...,9,10

I heard using a for loop would work but I am completely stuck on how to move
through this problem.

All help is greatly appreciated,

Kurt

you can try

for k=-10:1:10

c(k+11) = here you enter the Ck equation; % you cant have negative indexing in MATLAB

end

Now

c gives you the coefficients

rgds

I need to find the fourier series coefficients, ck, with

k=-10,-9,... ,9,10

Hey..

For fourier coeff u have to find the fft of the given sequence using matlab.

Since u have to find the coeff for kranging from -10:1:10, i.e.21 points u

have to define ur function in time domain in 21 samples. Take the fft of

these 21 samples. The resultant is your desired fourier coeff .
