Adaptive High Q Notch Filter.
Abstract
The report develops the information, techniques, and circuitry for the realization of an adaptive notch filter. The principal application, considered in the filter design, was for the operation of the adaptive notch in conjunction with a real time signal processor. The design equation expresses the circuit components for the independent control of the filter response in terms of the desired filter characteristics of notch width, notch depth, and center frequency. The experimental evaluation includes the adaptive characteristics, the transient behavior associated with the adaptation of the filter as well as the usual characteristics of system bandwidth, self noise, dynamic range and performance variation with temperature. The achieved performance establishes high expectations for the incorporation of an adaptive notch in a real time signal processor. (Author)
