Optimum notch filtering

WebNotch filter A ``notch filter'' rejects a narrow frequency band and leaves the rest of the spectrum little changed. The most common example is 60-Hz noise from power lines. A notch filter is a filter that filters out a particular frequency from a signal. Notch filters: are used to remove repetitive "Spectral" noise from an image ...

WebJun 21, 2024 · When we apply a filter (on any stationary signal to start with) we eliminate or attenuate part of the bandwidth and amplify the other part. So for instance if your noise is white noise (equally spread in all frequencies) and your signal is band limited to say bandwidth B, then the "optimal" filter is essentially filter that allows only the band B.
