چکیده

We develop a canonical, adaptive cascade-structure IIR notch filter to detect and track multiple time-varying frequencies in additive white Gaussian noise. The algorithm uses allpass frequency transformation filters and a truncated gradient. Simulations indicate that our algorithm is computationally simple, converges rapidly, and has good frequency resolution.

Rfi Cancellation in Vdsl Systems Using a Novel Complex

A complex−allpass−based multiple notch IIR filter is proposed to suppress Radio Frequency Interference (RFI) that affect VDSL systems. A notch filter realization based on complex allpass cascaded second−order sections is presented and evaluated in this paper. Two different algorithms, using the Recursive Prediction Error (RPE) method and an alternative (similar to the Steiglitz−McBride) method,...

IIR Multiple Notch Filter Design Based on Allpass Filter

In this paper, real coefficient IIR notch filter design problem is investigated. The specification of notch filter is first transformed into that of allpass filter. Then, we develop an effective approach to design this desired allpass filter. The realization of proposed notch filter is equivalent to the realization of an allpass filter. Due to the mirror-image symmetry relation between the nume...

An adaptive, high-order, notch filter using all pass sections

A fully adaptive infinite impulse response notah filter in cascade form is proposed to detect and track multiple time-varying frequencies in additive white noise. Based on transformations for digital filters in the frequency domain, the filter results in a minimal number of parameters. In addition, a simple adaptive algorithm with good tracking and convergence properties is obtained by using al...

Low Sensitivity Design of Multiplierless Elliptic Iir Digital Filters

In this paper an improved method of design of low sensitivity multiplierless elliptic IIR digital filters is proposed. The design technique is based on the sensitivity analysis and a selection of proper allpass sections. The allpass sections used to realize the allpass structures are with minimized sensitivities. Using the symbolic analysis, the expressions for phase sensitivities to multiplier...
