Signals & System Theory - DTFT/Fourier Series

Problem:

- Using known DTFT's or results derived in class, determine the complex Fourier series coefficients of the following periodic signal. In each case, also give the value of the fundamental period for this signal

Some of DTFT derivations:

-

- Say that .

DTFT counterpart of x(t) is

-

*DTFT derivations can be used to help solving this problem.

*Be as detailed and written clearly please! Thank you.

TO x(t) = 5 13 - 12cos(2nt) sin(na) s[n] = = DTFT S(e) = {1, W
