摘要： A side-tone control unit for a telecommunication instrument is configured to include a side-tone amplifier having a transfer function selectively controlled in accordance with a set of amplifier parameters, and a side-tone controller, coupled to the side-tone amplifier, for selectively applying the set of amplifier parameters to the side-tone amplifier based on the detected energy of an uplink signal and the detected energy of a downlink signal. The side tone controller can select a particular set of amplifier parameters by indexing a table in accordance with quantized values of the detected uplink signal energy and the detected downlink signal energy.
