Unformatted text preview: EECS 20. Midterm No. 2 April 16, 2002. Please use these sheets for your answer and your work. Use the backs if necessary. Write clearly and put a box around your an swer, and show your work. Print your name and lab TAs name below Name: Lab TA: Problem 1: Problem 2: Problem 3: Problem 4: Total: 1 1. 30 points. Consider a continuoustime signal x : Reals Reals defined by t Reals, x ( t ) = 3 + 2sin(3 t ) + 3cos(4 t ) . (a) Obtain the Fourier series coefficients of x ( t ) , i.e., find the coefficients A ,A 1 ,A 2 ,... and 1 , 2 ,... and w such that x ( t ) = A + X k =1 A k cos( kw t + k ) . (b) Obtain the Fourier series expansion for x ( t ) , i.e., find the coefficients X k for all k Integers such that x ( t ) = X k = X k e ikw t . 2 (c) Consider a continuoustime LTI system Filter : [ Reals Reals ] [ Reals Reals ] with the following frequency response: H ( w ) = 2 ,  w  2 , H ( w ) = 0 ,  w  < 2 ....
