5.44. The impulse responses of four linear-phase FIR filters hi[n], h2[n],h3[n], and h4n]are given below. Moreover, four magnitude response plots, A, B. C, and D, that potentially corre- spond to these impulse responses are shown in Figure P5.44. For each impulse response hi[n 1.....4, specify which of the four magnitude response plots, if any, corresponds to it. If none of the magnitude response plots matches a given hi[n, then specify "none as the answer for that hiIn] h1 [n] :...
