Filtering is the oldest and most common type of signal processing, usually in the form of frequency selectivity or phase shaping, or both. Some examples of filter applications:
- Extracting a desired signal from other signals,
- Separating signals from noise,
- Anti-aliasing in analog-to-digital converters or smoothing in digital-to-analog converters,
- Phase equalization, and
- Limiting amplifier bandwidths for reducing noise, etc.
