Filter - Signal Processing

Signal Processing

In signal processing, especially electronics, an algorithm or device for removing part(s) of a signal:

• Filter (signal processing), especially,
  • Electronic filter, an electronic circuit which processes signals, for example to remove unwanted frequency components
  • Digital filter, a system that performs mathematical operations to reduce or enhance certain aspects of a signal
  • Analogue filter, a basic building block of signal processing much used in electronics, see Passive analogue filter development
