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 ˆ x 10 ( t ) = ∑ 10 k =10 a k e jkω 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.
