Interference of power line (PLI)(fundamental frequency and its harmonics) is usually present
in biopotential measurements. Despite all countermeasures, the PLI still corrupts …

In signal processing it is often required to have multiple-notch filters which simultaneously
possess a very selective magnitude response and a transient response of short duration …

The paper investigates the design methods for the minimum-order allpass-based infinite
impulse response multi-notch filters. Monotonically decreasing nature of the stable allpass …

A method for multi-frequency notch filtering is described. The approach is based on
quadratic programming, which leads to projecting the signal vector onto the orthogonal …

The acquisition of the fetal electrocardiogram (fECG) signal via abdominal electrodes placed
on the maternal abdomen represents an alternative method to the one used currently in …

Source separation in digital signal processing consists of finding best estimates of the
signals involved in a signal mixture. Although, in most cases a detailed information about the …

Interference of power line (PLI)(fundamental frequency and its harmonics) is usually present
in biopotential measurements. Despite all countermeasures, the PLI still corrupts …

In this paper, a new variable step size LMS algorithm is proposed. The proposed algorithm
uses the estimated correlation between the reference and error signal of the adaptive filter …
