Latest Patents

Niina holds a patent for an echo suppressor designed for communication systems. This device addresses the issue of echo in audio transmissions, where a signal sent to a transmitting line is returned to a receiving line with some delay. The suppressor includes an attenuator that reduces the amplitude of a received speech signal. By comparing the amplitude levels of transmitting and receiving speech signals, the device generates a control signal for the attenuator. The delay time for this control signal is carefully managed to ensure that the echo from a near-end user is suppressed without affecting the clarity of speech from a far-end user.
