Title: Innovations of Sung M Yang in Echo Cancellation Technology.
Introduction
Sung M Yang is a notable inventor based in Newark, CA (US). He has made significant contributions to the field of communication technology, particularly in echo cancellation systems. His innovative approach has led to the development of a unique patent that addresses common challenges in voice-frequency communication circuits.
Latest Patents
Sung M Yang holds a patent for an "Echo canceller using end delay measurement." This invention involves an echo canceller that is connected in the four-wire, voice-frequency path of a communication circuit. The system includes an end delay analyzer that bridges the four-wire transmit and receive paths. It features a variable delay and an echo synthesizer connected in series between the received signal path and one input of a summation circuit. The other input to the summation circuit is linked to the four-wire transmit path, where the return echo signal propagates. Any difference that arises appears as a residual echo at the output of the summation circuit. The end delay analyzer provides an output control signal that adjusts the variable delay to compensate for terminal circuit delays, simplifying the echo synthesizer structure.
