1. In IIR Filter design by the Bilinear Transformation, the Bilinear Transformation is a mapping from a) Z-plane to S-plane b) S-plane to Z-plane c) S-plane to J-plane d) J-plane to Z-plane AnswerAnswer: b [Reason:] From the equation, it is clear that transformation occurs from s-plane to z-plane 2. In Bilinear Transformation, aliasing of frequency…
