What are the steps involved to design digital filter using bilinear transformation?
When designing a digital filter using an analog approximation and the bilinear transform, we follow these steps:
1Prewarp the cutoff frequencies.
2) Design the necessary analog filter.
3) Apply the bilinear transform to the transfer function.tan(ω/2) or ω = 2 tan−1(ΩTd/2).
This nonlinear relationship is called “frequency warping”.
What is the design of bilinear transformation?
The bilinear transformation is a mathematical mapping of variables.
In digital filtering, it is a standard method of mapping the s or analog plane into the z or digital plane.
It transforms analog filters, designed using classical filter design techniques, into their discrete equivalents.
