Which is bilinear transformation?

The bilinear transform (also known as Tustin's method, after Arnold Tustin) is used in digital signal processing and discrete-time control theory to transform continuous-time system representations to discrete-time and vice versa. with first order all-pass filters.

Why is it called bilinear transformation?

First of all, it is called bilinear because the numerator and the denominator are linear in z. Second of all, the bilinear transform maps the left half-plane of the s-plane into the interior of of the unit circle in the z-plane.

How do you find the bilinear transformation?

A bilinear transformation w = f(z) with more than two fixed points in the extended complex plane must be the identity transformation. where k is a constant. If | k | = 1, k = 1, then it is called elliptic transformation and if k > 0 is real, then it is called hyperbolic transformation.
