Abstract
Active Noise Control (ANC) systems can be used for suppressing sinusoidal frequency interference in wideband signals. In some applications it may be desirable to limit the maximum power level delivered by the ANC system to prevent overdriving a transducer or causing output amplifier saturation. This paper develops an algorithm for an adaptive IIR filter that places a constraint on the output power level, while still maintaining a narrow bandwidth to reject only the interfering sinusoidal portion.
