Patent

CA 2193152

A telephone handset interface is disclosed for reducing or eliminating feedback induced singing in a telephone handset/hybrid loop. The interface provides for user selectable volume control settings, each setting representing an amount of gain or loss to be applied to the transmit and receive signals within the telephone set. The gain settings are selected to limit overall loop gain so as to reduce or eliminate any tendency of the handset to sing at high receive gain levels. Loss inserted into the transmit circuit is removed when user speech is detected in the transmit circuit.

L'invention est une interface de combiné téléphonique servant à réduire ou à éliminer les autoexcitations induites par rétroaction dans les boucles de combiné téléphonique. L'interface permet à l'utilisateur de choisir des niveaux de volume, chaque niveau représentant un gain ou un affaiblissement à appliquer aux signaux émis et reçus avec le téléphone. Les niveaux de gain sont choisis de façon à limiter le gain global de la boucle afin de réduire ou d'éliminer toute tendance du combiné à entrer en autoexcitation quand le gain appliqué aux signaux reçus est élevé. L'affaiblissement introduit dans le circuit d'émission est supprimé quand les paroles de l'utilisateur sont détectées dans ce circuit.
