Title: Edwin A. Stennett: Innovator in Echo Cancellation Technology

Introduction

Edwin A. Stennett is a notable inventor based in Gaithersburg, MD (US). He has made significant contributions to the field of communication technology, particularly in echo cancellation systems. His innovative work has led to the development of a unique patent that addresses challenges in signal processing.

Latest Patents

Stennett holds a patent for a "Double talk and line noise detector for an echo canceller." This invention comprises an adaptive finite impulse response filter that receives a signal and has its output subtracted from a send signal. The system includes a non-linear device that attenuates low-level signals of the send signal and a noise injector that introduces noise into the send signal, proportional to dynamically measured background noise in the subtracted output. The non-linear device and noise injector are disabled when the receive signal is below the expected noise level or when the send signal is at a high level relative to the receive signal. This innovative approach enhances the performance of echo cancellers in communication systems.
