ECG INTERFERENCE SUPPRESSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240313751 titled 'ECG INTERFERENCE SUPPRESSION

The circuit described in the abstract consists of an interference frequency tracking circuit, a PLI synthesizer circuit, and a summing circuit. The interference frequency tracking circuit tracks the frequency of an interference signal derived from a target signal and provides a frequency selection value representing the interference signal's frequency. The PLI synthesizer circuit generates a correction signal at the interference signal's frequency, adjusts the phase and amplitude of the correction signal to match those of the interference signal in the target signal. The summing circuit subtracts the correction signal from the target signal.

• Interference frequency tracking circuit tracks interference signal frequency
• PLI synthesizer circuit generates correction signal at interference signal frequency
• PLI synthesizer circuit adjusts phase and amplitude of correction signal to match interference signal in target signal
• Summing circuit subtracts correction signal from target signal

Potential Applications: - Signal processing systems - Communication devices - Radar systems

Problems Solved: - Minimizing interference in target signals - Improving signal quality
