Abstract
A system for processing a repeating complex waveform that removes or reduces a significant portion of artifacts and other noise from the desired source signal. The system employs a phase detector for isolating artifacts from the source which are then used in processing the ECG waveform. The method and apparatus is especially useful in processing ECG signals reflective of heart conditions. The resulting clean signal makes accurate diagnosis of pending patient condition faster and more reliable.
