Abstract
A notch filter appropriately adjusts the amount of attenuation at a center frequency of its notch band through changing or adjusting a value of an adjustable parameter A, and adaptively controls the amount of signal attenuation of a predetermined frequency component for an input signal that passes the notch filter, so as to partially suppress or partially attenuates the predetermined frequency component without affecting the size of a bandwidth of the notch filter.
