   Filters, IF

Electronic filters are electronic circuits which perform signal processing functions, specifically intended to remove unwanted signal components and/or enhance wanted ones. Electronic filters or audio filters can be:

  • passive or active
  • analog or digital
  • discrete-time (sampled) or continuous-time
  • linear or non-linear
  • infinite impulse response (IIR type) or finite impulse response (FIR type)

The most common types of electronic filters are linear filters, regardless of other aspects of their design. See the article on linear filters for details on their design and analysis.
