device and process for compensating noise signals in analog telephony signals

摘要

patent and device for noise signal compensation in analog telephony signals. The present invention relates to a device (200) having an interface (210) for transmitting an analog telephony signal. The device also has a compensation circuit (350, 360) which detects a noise signal in the analog telephony signal, generates a compensation signal (cmp) that is phase-opposed to the noise signal, and combines the compensation signal. (cmp) with the analog telephony signal.
