Question: The impulse responses of four linear-phase FIR filters h [n], h [n], h3 [n], and h [n] are given below. h [n] = -6[n]

The impulse responses of four linear-phase FIR filters h [n], h [n], h3 [n], and h [n] are given below. h [n]

The impulse responses of four linear-phase FIR filters h [n], h [n], h3 [n], and h [n] are given below. h [n] = -6[n] -0.58[n 1] +8[n-2] - 8[n-4] +0.58[n - 5] + [n-6] h [n] = 0.48 [n] -0.38 [n 1] +0.58[n-2] -0.38[n- 3] +0.48 [n-4] h3 [n] = 0.58[n] -0.78[n 1] +0.58[n-2] -0.58[n- 3] +0.78[n-4] -0.58 [n- 5] h4[n] = 0.68[n] + 1.58[n 1] + [n-2] + [n- 3] +1.58[n - 4] +0.68[n - 5] - 1) Plot the magnitude and phase responses of each filter ii) Sketch the pole-zero plot of each filter iii) Determine the type of each filter (i.e Type I, Type II, Type III or Type IV). Explain your answer.
