Question:

We wish to design an FIR lowpass filter satisfying the specifications

0.98 < H(e^jω) < 1.02, 0 ≤ |ω| ≤ 0.63π,

−0.15 < H(e^jω) < 0.15, 0.65π ≤ |ω| ≤ π,

by applying a Kaiser window to the impulse response h_d[n] for the ideal discrete-time lowpass filter with cutoff ω_c = 0.64π. Find the values of β and M required to satisfy this specification.
