An Automatic Design Procedure for Low-order IIR Parametric Equalizers An optimization procedure is presented for the automatic design of a low-order equalizer using parametric infinite impulse response (IIR) filters, specifically second-order peaking filters and first-order shelving filters. The proposed...
A modified second-order infinite impulse response (IIR) notch filter with constrained poles and zeros is presented to eliminate or retrieve sinusoids embedded in a broadband signal. Such a filter is ideally suited to either parallel or cascaded implementation. Two classes of problems are considered....

Adaptive Notch FilterArctangent gradient algorithmFrequency estimation based on adaptive notch filter is very attractive due to simplicity and economy. This paper presents an arctangent gradient (AG) based adaptive algorithm for a secondorder constrained adaptive IIR notch filter (ANF). The...
In this paper it is shown that the FIR notch filters obtained from standard 2nd-order IIR filters are inadequate, and an alternate 2nd-order IIR notch filter is proposed, which provides an unbiased estimate of the frequency. The FIR filter obtained from the new IIR filter provides a closed-...
