Consider the following ideal frequency response for a multiband filter:

The impulse response h_d[n] is multiplied by a Kaiser window with M = 48 and β = 3.68, resulting in a linear-phase FIR system with impulse response h[n].

(a) What is the delay of the filter?

(b) Determine the ideal desired impulse response h_d[n].

(c) Determine the set of approximation error specifications that is satisfied by the FIR filter; i.e., determine the parameters δ₁, δ₂, δ₃, B, C, ω_p1, ω_s1, ω_s2, and ω_p2 in
