Adaptive Universal Linear Filtering

IEEE Transactions on Signal Processing, 2013
We consider the problem of online estimation of an arbitrary real-valued signal corrupted by zero-mean noise using linear estimators. The estimator is required to iteratively predict the underlying signal based on the current and several last noisy observations, and its performance is measured by the mean-square-error.

Universal Filtering Via Prediction

IEEE Transactions on Information Theory, 2007
We consider the filtering problem, where a finite-alphabet individual sequence is corrupted by a discrete memoryless channel, and the goal is to causally estimate each sequence component based on the past and present noisy observations. We establish a correspondence between the filtering problem and the problem of prediction of individual sequences ...

A universal notch filter

International Journal of Circuit Theory and Applications, 1979
Recently an active RC configuration for realizing a second-order allpass or a symmetrical notch responses has been given.' The circuit is capable of realizing a high pole Q and has the attractive feature of providing a constant gain factor of unity. In this letter a worthy modification is added to the network' in order to provide any notch response ...

Nyquist 1 universal filters

IEEE Transactions on Communications, 2000
The Nyquist (1928) 1 filters (NFls) with both nonlinear phase response and amplitude response of nonspecified symmetry are investigated. It is shown that one of the filter's responses (amplitude or phase) can be chosen almost arbitrary. The second one is then derived from the condition of zero intersymbol interference (ISI) in data transmission ...

SINH-DOMAIN UNIVERSAL BIQUAD FILTERS

Journal of Circuits, Systems and Computers, 2014
A family of current-mode universal biquad filters, realized using the concept of Sinh-Domain signal processing, is introduced in this paper. Both of them have the capability for operating in a low-voltage environment and, also, for orthogonal electronic adjustment between the resonance frequency and Q factor.
