  • Howling controller
    Patent number: 6590974
    Abstract: A digital signal processing algorithm to cancel howling in a telephone circuit, the telephone circuit being characterized by a receive path and a transmit path in an effective closed loop configuration. The algorithm monitors input samples taken from the receive path and, if a howling signal is detected, controlled amounts of attenuation are introduced to the loop until howling is cancelled. In a preferred embodiment a prediction logic is included in the algorithm to verify the howling signal.
