Unformatted text preview: ENEE 241 02 * HOMEWORK ASSIGNMENT 37 Due Mon 05/12 A FIR filter acts on the input sequence given by x [0 : 5] = £ 1 3 5 2 6 2 / T ; x [ n ] = 0 for n < 0 and n > 5 to produce the output sequence given by y [0 : 11] = £ 2 3 0 10 23 27 61 51 54 14 2 / T and y [ n ] = 0 for n < 0 and n > 11. (i) (2 pts.) What is the length of the filter coefficient vector b ? (As usual, it is assumed that the first and last entries in b are nonzero.) (ii) (6 pts.) Use the FFT command in MATLAB to determine the coefficient vector b . (Alterna tively, b can be determined by solving a triangular system of linear equations.) (iii) (6 pts.) Without performing a convolution, determine the response of the filter to the input sequence x (1) [ · ] whose nonzero entries are x (1) [0 : 11] = £ 1 3 5 2 6 2 1 3 5 2 6 2 / T (iv) (6 pts.) Without performing a convolution, determine the response of the filter to the input sequence x (2) [ · ] whose nonzero entries are x (2) [0 : 9] = £ 2 6 10 4 11 7 5 2...
