Description | ||||||||

The module contains a function for performing the bilinear transform. The input is a rational polynomial representation of the s-domain function to be transformed. In the bilinear transform, we substitute 2 1 - z^-1 s <-- -- * -------- ts 1 + z^-1 into the rational polynomial, where ts is the sampling period. To get a rational polynomial back, we use the following method: - Substitute s^n with (2/ts * (1-z^-1))^n == [ -2/ts, 2/ts ]^n
2. Multiply the results by (1+z^-1)^n == [ 1, 1 ]^n 3. Add up all of the common terms 4. Normalize all of the coeficients by a0 where n is the maximum order of the numerator and denominator | ||||||||
