The current cascade form adaptive notch filters have two different ways to adjust its
parameters. First, each section is adapted individually (AI). Second, all sections are adapted …

In this paper we propose a new simplified algorithm for cascaded second order adaptive
notch filters implemented using an allpass filter, for elimination of multiple sinusoids. Each of …

This paper introduces a new family of infinite impulse response adaptive notch filters that
forms multiple notches using a second-order factorization of an all-pass transfer function …

A new type of complex adaptive notch filter is developed, which is capable of tracking
multiple complex sinusoidal signals. The proposed complex structure is developed from an …

A cascaded second order notch filter implemented using an allpass filter, for elimination of
multiple sinusoids, have been proposed. Various adaptive algorithms for the adaptive notch …

In this paper, three new methods for two-dimensional (2-D) adaptive notch filter (ANF) are
proposed. They not only contain similar and simpler structures but also can be derived by …

In this paper, we present a new structure for the complex adaptive IIR notch filter which is
useful for the detection of complex sinusoids in communication and radar systems. The …

In this paper we propose a parallel composition based adaptive notch filter for eliminating
sinusoidal signals whose frequencies are unknown. The proposed filter which is …

In this letter, a new structure of adaptive IIR notch filter is presented. The structure is based
on direct form realization and uses the similar adaptation algorithm given in Ref.(4). A …

We propose two adaptive notch filters (ANFs) for sinusoids embedded in a noisy
environment. Both of the ANFs, as usual, are structurally composed of a time-variant infinite …
