Member of the filter implementation class.

Syntax

[num2, den2] = bilinear(num1, den1, fs)

[num2, den2] = bilinear(num1, den1, fs, fp)

[z2, p2, k2] = bilinear(z1, p1, k1, fs)

[z2, p2, k2] = bilinear(z1, p1, k1, fs, fp)

[a2, b2, c2, d2] = bilinear(a1, b1, c1, d1, fs)

[a2, b2, c2, d2] = bilinear(a1, b1, c1, d1, fs, fp)

Description

Computes a bilinear transform with optional frequency prewarping.
