Abstract
During echo suppression in a system utilizing a split echo suppressor, suppression is removed when the near-end party breaks in (i.e., during double talking) and is typically replaced with a small fixed loss inserted in the receive line. To minimize loud echoes without unduly penalizing soft talkers at the far end, the loss inserted in the receive line can be varied advantageously according to the incoming signal level by using a compression circuit. The present disclosure relates to a simple arrangement for providing instantaneous compression loss in a digital system by modifying the incoming encoded signal in a predetermined manner. In an illustrative embodiment, one-half the value of the input signal is added to one-half of a selected value when the input signal level equals or exceeds the selected value.
