Unformatted text preview: a k for the following continuous-time periodic signal x ( t ) : x ( t ) = 1 . 5 , t < 1-1 . 5 , 1 t < 2 with fundamental frequency = . Problem 4. Fourier Series Representation Let x 1 ( t ) be a continuous-time periodic signal with fundamental frequency 1 and Fourier series coefcients a k . Now, dene x 2 ( t ) as follows: x 2 ( t ) = x 1 (1-t ) + x 1 ( t-1) . (a) What is the fundamental frequency 2 of the signal x 2 ( t ) ? (b) Find the relationship between the Fourier coefcients b k of x 2 ( t ) and the coefcients a k ....
