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 …

This paper presents a technique for designing a notch filter with controlled null width. The
basic idea is to minimize the mean square error between the desired unity response and the …

In this paper, a real-time cascade adaptive notch filter scheme for sinusoidal parameter
estimation is proposed. The second order recursive maximum likelihood algorithm is used to …

Most traditional wire rope sensors produce the integrated volume of magnetic leakage
around the whole circumference of wire rope, which is insensitive to the circumferential …

This paper is aimed at finding parametric signal models that perform well at modelling noisy
tonals at low signal-to-noise ratios (SNRs). We focus on models that are applied to a …

In this paper, the two dimensional (2D) IIR digital notch filter design problem is investigated.
First, we develop a simple algebraic method for 2D IIR notch filter design. This approach not …

A new IIR adaptive algorithm for separating, enhancing and tracking multiple sinusoids is
investigated. In this algorithm, up to M complex sinusoids are individually tracked by passing …
