What Are The Advantages & Disadvantages Of Bilinear Transformation?

Answer»

ADVANTAGES:

  • The bilinear transformation provides one-to-one mapping.
  • Stable continuous SYSTEMS can be MAPPED into realizable, stable digital systems.
  • There is no aliasing.

Disadvantage:

  • The mapping is highly non-linear PRODUCING frequency, COMPRESSION at high frequencies.
  • Neither the impulse response nor the phase response of the analog filter is preserved in a digital filter obtained by bilinear transformation.
