During lab 4, we have seen numerical implementation of Fourier Series for periodic signals. As first part of this assignment, you need to write a Matlab function that would take an array representing a single period of a signal (x), corresponding time array (t), and return the Fourier Series coefficients (Ck) in exponential form. The function should also be able to take two (2) optional input arguments: number of Fourier coefficients (Nk) and plot option (p). Use the template ‘fourier_series_exp.m’...

Problems 123 If f(n) is a periodic sequence with period N, it is also periodic with period 2N. Tet 8(k) denote the DFS coefficients of X(n) considered as a periodic sequence with period N and X,(k) denote the DFS coefficients of x(n) considered as a periodic sequence with period 2N. X,(k) is, of course, periodic with period N and X2(k) is periodic with period 2N. Determine 8(k) in terms of X (k). 5. Consider two...

1. (15 points) Review Carefully read each statement below and identify it as True or False and, for each answer, explain your reasoning briefly in 1-2 sentences. 1. A 100KHz tone (i.e., sinusoid) is input to an LTI system. The frequency spectrum of the output signal may include components at integer multiples of 100KHz. True or False? Why? 2. The phase of the Fourier transform of a real-valued signal with odd symmetry will always be +90 deg. True or False?...
