Abstract :
Adaptive notch filters are used to eliminate narrow-band or sine wave components with unknown or slowly time varying frequencies from observed time series. This paper derives the asymptotic bias and variance of the sine wave frequency estimate obtained by the adaptive notch filter recently proposed in [4].
