Question

5.38 a,b,c

aliasing occur? (Justify your answer.) 5.38. An ideal lowpass digital filter has the frequency function H(2) given by H(n) (a) Determine the unit pulse response h[n] of the filter. (b) Compute the output response yln] of the filter when the input [n] is given by (i) x[n] = cos(m/8), n = 0, ±1, ±2, . . . (ii) x[n] = cos(3rm4) + cos(πη/16), n = 0, ±1, ±2,… (iii) x[n]-sinc(n/2), n-0, ±1,±2 (iv) x[n] = sine(n/4), n = 0, ±1,±2, (v) x[n]-sine(nB) cos(mz/8), n-0, ±1, ±2 (vi) x[n] = sine(n/8) cos(mz/4), n = 0, ±1,±2, (c) For each signal defined in part (b). plot the input [n and the corresponding output y[n] to determine the effect of the filter
