Question: Suppose that we wish to design a highpass filter satisfying the following specification: 0.04 < |H(e j )| < 0.04, 0 || 0.2,
Suppose that we wish to design a highpass filter satisfying the following specification:
−0.04 < |H(ejω)| < 0.04, 0 ≤ |ω| ≤ 0.2π,
0.995 < |H(ejω)| < 1.005, 0.3π ≤ |ω| ≤ π.
The filter will be designed using the bilinear transformation and T = 2 ms with a prototype continuous-time filter. State the specifications that should be used to design the prototype continuous-time filter to ensure that the specifications for the discrete-time filter are met.
