ECG INTERFERENCE SUPPRESSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18589715 titled 'ECG INTERFERENCE SUPPRESSION

The circuit described in the patent application 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 frequency of the interference signal based on the frequency selection value. It 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.

Potential Applications: - This technology could be used in communication systems to mitigate interference and improve signal quality. - It may find applications in radar systems to enhance target detection accuracy by reducing interference.

Problems Solved: - Addresses interference issues in signals that can degrade performance. - Improves the accuracy and reliability of target signal processing.

Benefits: - Enhances signal quality by reducing interference. - Improves overall system performance and accuracy.

Commercial Applications: Title: Advanced Signal Processing Technology for Enhanced Communication Systems This technology could be utilized in telecommunications equipment, radar systems, and other signal processing applications to enhance performance and reliability.

Questions about the technology: 1. How does the interference frequency tracking circuit determine the frequency of the interference signal? 2. What are the key advantages of using the PLI synthesizer circuit in signal processing applications?

Original Abstract Submitted

A circuit includes an interference frequency tracking circuit, a PLI synthesizer circuit, and a summing circuit. The interference frequency tracking circuit is configured to track a frequency of an interference signal derived from a target signal, and provide a frequency selection value representing the frequency of the interference signal. The PLI synthesizer circuit is configured to generate, based on the frequency selection value, a correction signal at the frequency of the interference signal, adjust a phase of the correction signal to match a phase of the interference signal in the target signal, and adjust an amplitude of the correction signal to match an amplitude of the interference signal in the target signal. The summing circuit is configured to subtract the correction signal from the target signal.
