Distinguish Between Fir Filters And Iir Filters?

Answer»

FIR filter:

  • IR filter
  • These filters can be easily designed to have perfectly linear phase.
  • FIR filters can be realized recursively and non-recursively.
  • Greater flexibility to control the shape of their magnitude RESPONSE.
  • ERRORS due to ROUND off NOISE are less severe in FIR filters, mainly because feedback is not used.

IIR filter:

  • These filters do not have linear phase.
  • IIR filters are easily realized recursively.
  • Less flexibility, usually limited to specific kind of filters.
  • The round off noise in IIR filters is more.

FIR filter:

IIR filter:
