Unformatted text preview: x ( t ) = et 2 ,2 t < 2. (a) Use Matlab to compute the complex exponential Fourier series { a k } for10 k 10. (b) Plot x ( t ) and the 10th order approximation x 10 ( t ) = 10 k =10 a k e jk t for5 t 5. Comment on how good the approximation is. (c) Play around with higher and lower order approximations and report on the results. Problem 3 (a) Fourier transform computation 4.1 (b) Fourier transform application Find an explicit expression for the output of the system in Problem 4.1(b) when the input is sin(10 t )....
