Background Modern biomedical amplifiers have a very high common mode rejection ratio.
Nevertheless, recordings are often contaminated by residual power-line interference …

The subjects considered in this article follow the logical procedures of acquisition,
preprocessing, wave detection, parameter measurement, and recording of the ECG. The …

Automatic detection of QRS onset and offset points with reasonable accuracy has been a
difficult task, approached since the first attempts at computerised electrocardiogram …

Power-line interference is always a problem when biopotential signals are recorded. This
paper presents a technique for time-efficient power-line interference suppression from EMG …

Abstract Power-line-interference (PLI) is one of the major disturbing factors in almost all
ground-free biopotential acquisition applications. The body is a volume conductor and …

The efficiency of notch filters and a subtraction procedure for power-line interference
cancellation in electrocardiogram (ECG) signals is assessed. In contrast with the subtraction …

Timing characterisation of the ECG using wavelet transforms is a new technique in which
multiscale analysis reduces the influence of noise. This technique issued to investigate the …

A method for reduction of power line interference (PLI) in electrocardiograms with sampling
rate integer multiple of the nominal power line frequency is developed and tested using …

The paper describes a method, based on a genetic algorithm, to remove sinusoidal
powerline interference in electrocardiograms. There is a report on the use of the genetic …

The paper deals with some aspects of the subtraction procedure, which removes the power-
line interference (PLI) without affecting the components intrinsic to ECG. This procedure is …
