Abstract
A multi-filter-set active adaptive control system includes a plurality of output transducer arrays introducing control signals to combine with a system input signal to yield a system output signal. A plurality of error transducers sense the system output signal and provide a plurality of error signals to a plurality of sets of adaptive filters. A plurality of sets of D/A converters are provided at the outputs of the adaptive filters outputting correction signals therethrough. A plurality of sets of A/D converters are provided at the filter inputs and error inputs of the adaptive filters. Various filter sets and combinations are provided.
