Consider the following signal:
cos(20nt)
te [-1, 1]
x(t)
te [-2, –1) u (1,2]
Assuming the signal is periodic with period T= 4,
find the Fourier series coefficients. In this case the
signal repeats at 4, -4, etc.
%3D
Then assume that the signal is not periodic, find
the Fourier transform. In this case the signal is zero
elsewhere, i.e., the signal is nonzero only for t
[-1,1].
