A class of complementary IIR filters

ISCAS'99. Proceedings of the 1999 IEEE International Symposium on Circuits and Systems VLSI (Cat. No.99CH36349), 2003
A class of complementary IIR filters is introduced. One of these filters can be realized as a tapped cascaded interconnection of identical allpass subfilters. The complementary filter is then obtained automatically by adding some extra allpass subfilters and a subtractor.

Multi-complementary filter bank

IEEE International Conference on Acoustics Speech and Signal Processing, 1993
An octave-spaced complementary filter bank that provides aliasing-free subband signal processing and perfect reconstruction is presented. The transition bandwidth of the splitting filters can be controlled independently by basis filters, which in turn are realized by multirate complementary filters. The design of the filter bank is presented. >

A family of phase complementary filters

ICASSP '79. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
Phase Complementary filters are of use in situations where it is necessary to measure energy content of a signal, at a particular frequency. This paper describes a family of such filter functions, based on time windows of the general form tke-at, k, integer.

Higher order complementary filters

IEEE Transactions on Signal Processing, 1994
A higher order generalization of magnitude and power complementary filters is proposed. The proposed scheme is shown to have superior frequency characteristics compared to the ordinary complementary filters. Applications of these generalized complementary filters include subband coding for audio and video and sharpening of magnitude characteristics of ...

Broadband beamforming with power complementary filters

IEEE Transactions on Signal Processing, 2002
This paper addresses the design of broadband finite impulse response (FIR) beamformers with a power complementarity property. The power complementarity requirement is needed to preserve the whiteness of the channel noise at the beamformer output, which allows the application of optimum trellis-based equalizers to the output signal.

Complementary two-dimensional digital filters

Proceedings of the IEEE, 1986
The concept of complementary one-dimensional digital filters is extended here to the two-dimensional case. An application of the complementary two-dimensional filters is described and illustrated with the aid of an example.

A gyroless adaptation of attitude complementary filtering

2019 18th European Control Conference (ECC), 2019
This article proposes a methodology for estimating the attitude of a rigid body from vector measurements only, i.e. without gyrometers. Classically, two vector measurements are enough to determine the attitude of a rigid body, through an algebraic calculation which is sometimes considered as computationally costly or tedious to implement.

Complementary IIR digital filter banks

ICASSP '85. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1985
The class of digital filter pairs satisfying two types of complementary properties simultaneously is reexamined. The pair is required to have complementary square magnitude characteristics with respect to a constant and transfer functions complementary with respect to an allpass function.
