Advantages and disadvantages of bilinear transformation method

Bi-linear transformation method is one of the most important method is that transforming the analog filter into appropriate IIR filter. So here this article gives the information about advantages and disadvantages of bi-linear transformation to know more details about it.

Advantages of bi-linear transformation method  :
  • The mapping is one to one
  • There is no aliasing effect
  • Stable analog filter is transformed into the stable digital filter
  • There is no restriction one type of filter that can be transformed
  • There is one to one transformation from the s-domain to the Z- domain
Disadvantages of bi-linear transformation method :
  • The mapping is non linear in this method because of this frequency warping effect takes place
