In Bilinear Transformation, aliasing of frequency components is been avoided.

(a) True

(b) False

This question was posed to me in homework.

This intriguing question originated from IIR Filter Design by the Bilinear Transformation in chapter Discrete Time Systems Implementation of Digital Signal Processing

Best answer
The correct option is (a) True

The best I can explain: The bilinear transformation is a conformal mapping that transforms the jΩ-axis into the unit circle in the z-plane only once, thus avoiding the aliasing.
