A new IIR adaptive notch filter
A new IIR adaptive notch filter (ANF) with fast convergence rate, accurate estimation of notch frequencies, and modest realization complexity is presented in this paper. The problem of obtaining a notch filter from a given signal containing multiple sine waves in noise is first formulated as the conventional problem of system identification. Then the new ANF is developed via the algorithm of St...
متن کاملContinuous Circadian Phase Estimation Using Adaptive Notch Filter
Actigraphy has been widely used for the analysis of circadian rhythm. Current practice applies regression analysis to data from multiple days to estimate the circadian phase. This paper presents a filtering method for online processing of biometric data to estimate the circadian phase. We apply the proposed method on actigraphy data of fruit flies (Drosophila melanogaster).
متن کاملAttitude Control of Flexible Launch Vehicle Using Adaptive Notch Filter
Attitude control of a flexible launch vehicle is addressed in this study. A ground experimental model is developed for verification of different stabilization strategies. The experimental set up duplicates planar motion of flexible launch vehicles as a coupled hybrid dynamics of rigid body pitching motion and flexible vibration. In particular, adaptive notch filter, which updates filter paramet...
متن کاملAn 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...
متن کاملRealization of Adaptive NEXT canceller for ADSL on DSP kit
Crosstalk canceller plays a key role in achieving high bit rates in wire line multicarrier Asymmetric Digital Subscriber Line (ADSL) systems. Adjacent systems within a cable binder that transmit or receive data in the same frequency range can create crosstalk interference. In an ongoing effort to study and improve the performance of ADSL Central office and CPE modems, the effect of Near-end cro...
