Abstract :
It is shown that estimation accuracy of adaptive notch filters (ANFs) can be increased by combining two techniques that were previously used separately: automatic gain adjustment and frequency debiasing. To achieve this goal one has to solve a nontrivial problem of determining estimation delay introduced by a variable-gain ANF filter.
