What is bilinear transformation method?
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.
Which of the following is a bilinear transformation?
Which of the following rule is used in the bilinear transformation? Explanation: Bilinear transformation uses trapezoidal rule for integrating a continuous time function.
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.
What is the main problem of bilinear transformation?
Disadvantages of bi-linear transformation method :
The mapping is non linear in this method because of this frequency warping effect takes place.
