Latest Patents

Takeuchi holds a patent for an adaptive control type echo suppressor. This invention compares the levels of voice signals in sending and receiving paths using a first comparator. When the level of the voice signal in the receiving path exceeds that of the sending path, the sending path is cut off to suppress the echo. The system includes a control loop that applies the voice signal from the receiving path to a second comparator through a variable loss circuit. This setup allows for adaptive control of the variable loss circuit, effectively reducing the output of the second comparator to zero. The integrated values are obtained under a long time constant characteristic to minimize noise interference from both paths.
