Is there a Fourier Series for this function ?
graph is only showing y = 1
%% Problem 17.1_e
display('Problem 17.1_e')
syms t
A = 1.00;
B = exp(-t*pi*i);
C = exp(-t*pi*2*i)/2;
D = exp(-t*pi*3*i)/3;
f = A + B + C + D
ezplot(f,[0,(5*pi)/2]), grid on

Think about this question like this:
What is the Fouriertransform of a harmonically varying signal with constant amplitude and frequency?
How does that Fourier-transform vary with frequency and phase-shift?
When you've answered those two questions you will be able to extend the answer to your signal.
