The impulse responses of four linear-phase FIR filters h₁[n], h₂[n], h₃[n], and h₄[n] are given below. Moreover, four magnitude response plots, A,B,C, and D, that potentially correspond to these impulse responses are shown in Figure P5.44. For each impulse response h_i[n], i = 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 h_i[n], then specify “none” as the answer for that h_i[n].
