Question

Hi can you help me solve the following signal and system question on CTFS harmonic functions. Please show me how to get Cx[K] by integration by parts step by step. The graph for this question is not needed. Thank you.

4. A periodic signal x(t) with a period of 4 seconds is described over one fundamental period by x(t) 3-t, 0<t<4. Graph the signal and find its CTFS harmonic function. Then graph on the same scale approximations to the signal xN (t) given by of the grap h should cover at least for N = 1, 2 and 3 . (In each case the time scale two fundamental periods of the original signal.) Answer: cx[k]= 4 Tk2

Answer 1

Using Fourier Series analysis equation we get the solution.
