Question
This problem is about exponential Fourier Series
4) Consider a periodic signal f(t), with period To, that has a value of T/2t in the interval -t <t < t
and is identically zero in the rest of the interval from -T/2 to T/2.
A) Compute the exponential Fourier Series for f(t), which will be functions of To and t.
B) Take the limit of the part A answer as t goes to zero, and as a result find the exponential
Fourier Series for this limiting case, which is an impulse train (an impulse every T,
seconds).
