What is adaptive notch filter?
Adaptive Notch Filters (ANF) is well known as a variable notch filter of which notch frequency is controlled in real time by means of an adaptive algorithm. This adaptive mechanism allows automatic detection and removal of an unknown sinu- soid that is immersed in a wide-band signal such as a white noise.
What is the frequency of notch filter?
Notch filters can be useful on the command for a fixed-frequency noise source such as that from line frequency (50 or 60 Hz) noise. Notch filters are also used to remove resonances from the system. Both notch and low-pass filters can cure resonance; notch filters do so while creating less phase lag in the control loop.
What is an automatic notch filter?
Jul 25, 2021. A Notch Filter is also known as a Band Stop filter or Band Reject Filter. These filters reject/attenuate signals in a specific frequency band called the stop band frequency range and pass the signals above and below this band.
