Question: Wish to design an FIR lowpass filter satisfying the specifications 0.95 < H(e j ) < 1.05, 0 || 0.25, 0.1 < H(e

Wish to design an FIR lowpass filter satisfying the specifications

0.95 < H(e^jω) < 1.05, 0 ≤ |ω| ≤ 0.25π,

−0.1 < H(e^jω) < 0.1, 0.35π ≤ |ω| ≤ π,

by applying a window w[n] to the impulse response h_d[n] for the ideal discrete-time lowpass filter with cutoff ω_c = 0.3π. Which of the filters listed in Section 7.2.1 can be used to meet this specification? For each window that you claim will satisfy this specification, give the minimum length M+1 required for the filter
