Phasor diagram analysis of the LMS adaptive notch filter

In this paper the phasor analysis of the notch filter using adaptive canceling of sinusoidal interferences is given. Amplitude and phase characteristics are very clearly presented by phaser especially when the phase between reference signals is not exactly . Because of the output signal pulsation occurring in this case every other analysis is too complicated. This is a new approach and may be advantageous for more profound understanding of adaptive noise filtering.
