Abstract:
1. A level adjusting device for use with a near-end telephone, the near-end telephone being operable to generate an outgoing signal directed to a far-end telephone and to receive an incoming signal generated at least in part by the far-end telephone, the device comprising: a first signal processor operable to dynamically adjust a first signal level associated with the outgoing signal with reference to the first signal level; and a second signal processor operable to dynamically adjust a second signal level associated with the incoming signal with reference to the second signal level; wherein the first and second signal processors are further operable to control a loop gain to inhibit loop instability, and wherein the first and second signal processors are operable to dynamically adjust the first and second signal levels in a plurality of frequency bands and wherein the each of the first and second signal processors comprises a static gain control component and a dynamic gain control component.
