QUESTION: 11

Consider a continuous time periodic signal x(t) with fundamental period T and Fourier series coefficients X[k]. Determine the Fourier series coefficient of the signal y(t) given in question and choose correct option.

Que: y(t) = x(t - t_{0} ) + x (t - t_{0} )

Solution:

x(t - t_{0}) is also periodic with T. TheFourier series coefficients X_{1}[k] of x(t - t_{0}) are

QUESTION: 12
