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.

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.

Self balancing robot using complementary filter: Implementation and analysis of complementary filter on SBR

2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016
The Self balancing robot is based on the inverted pendulum concept, wherein an inverted pendulum is positioned on a cart and the cart is allowed to move on the horizontal axis so as to keep the pendulum in the upright position. This is a classic case of an unstable system.

Generalized doubly complementary IIR digital filters

Signal Processing, 1992
The authors examine the properties of weighted complementary IIR filters. Either real or complex allpass subfilters are utilized. The classical odd-order lowpass designs can be realized as a parallel connection of two real or complex conjugate allpass filters. Also, a complementary filter pair can be implemented at the cost of a single filter.

Non-causal complementary filters

Signal Processing, 1992
Introducing the idea of non-causal filtering into the design of complementary filter pairs, an extension of this filter is obtained. It is also shown that the magnitude of any non-causal complementary filter is the cosine of its phase. Using a lemma about non-causal polynomials for a given filter order, the number of poles outside the unit circle can ...

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 filter banks for image compression

Proceedings X Brazilian Symposium on Computer Graphics and Image Processing, 2002
In this paper we present a nonseparable complementary filter (CF) bank for image compression. We base our design of the filter bank on the two-dimensional (2D) multirate processing and on properties of complementary filters. Perfect reconstruction is guaranteed when the CF bank is implemented with quincunx sampling and filtering, but not otherwise.

Discrete time-varying attitude complementary filter

2009 American Control Conference, 2009
This paper presents the development of an attitude complementary filter for an Attitude and Heading Reference System (AHRS). Using strapdown inertial measurements and vector observations, the proposed complementary filter provides attitude estimates in Euler angles representation, while compensating for rate gyro bias.

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.

Generalized magnitude and power complementary filters

Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002
A new higher order generalization of magnitude and power complementary filters is proposed in this paper. 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 amplitude ...
