Abstract

A computer program was developed to simulate the recovery of late potentials in an ECG contaminated by noise. The frequency response of the averaging process characterized by a particular noise type and level was computed using its corresponding jitter sequence and sweeping the frequency of the simulated late potential signal from 40 to 2000 Hz. The results for 50 Hz and Gaussian noise are presented. It is also found that there is a negligible effect for Gaussian noise below 15 μV (rms) and 50 Hz noise below 5 μV.
