Abstract

A general adaptive system is presented to estimate deterministic recurrent transient signals time-locked to a stimulus. This system estimates the components of the deterministic signal using a function base and was applied to evoked potentials and electrocardiography (ECG) signals. For this adaptive system, the effect of misalignment errors in each signal recurrence is analyzed. The theoretical analysis shows that the errors in the occurrence time estimation produce a low-pass filtering effect with a cutoff frequency function of the error distribution. A simulation study with real ECG signals agrees with theoretical results.
