A periodic signal has the following Fourier series representation (a) Is x(t) band-limited? (b) Calculate the power

Question:

A periodic signal has the following Fourier series representation

x(t) (0.5k k=-00

(a) Is x(t) band-limited?

(b) Calculate the power P_x of x(t).

F(t) = E '0.5k jikt k=-N

by using 2N + 1 terms, find N so that xÌ‚(t)has 90% of P_x.

(d) If we use N found above, determine the sampling period that can be used to sample xÌ‚(t) without aliasing.
