Digital processing of EEG signals

IEEE Engineering in Medicine and Biology Magazine, 2001
The digitization of electroencephalogram (EEG) signal data is the essential first step in using computers to analyse and manipulate EEG data. EEG signals are inherently complicated due to their nonGaussian, nonstationary, and often nonlinear nature as shown by most of the articles of this special issue.

Soft digital signal processing

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2001
In this paper, we propose a framework for low-energy digital signal processing (DSP), where the supply voltage is scaled beyond the critical voltage imposed by the requirement to match the critical path delay to the throughput. This deliberate introduction of input-dependent errors leads to degradation in the algorithmic performance, which is ...

Digital processing of affective signals

Proceedings of the 1998 IEEE International Conference on Acoustics, Speech and Signal Processing, ICASSP '98 (Cat. No.98CH36181), 2002
Affective signal processing algorithms were developed to allow a digital computer to recognize the affective state of a user who is intentionally expressing that state. This paper describes the method used for collecting the training data, the feature extraction algorithms used and the results of pattern recognition using a Fisher linear discriminant ...

Circuits for digital signal processing

ICASSP '84. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
This paper discusses two custom integrated circuits designed to perform the functions of signal correlation and lattice filtering (MA or AR). Each circuit is decomposed into P operators, each being a direct implementation of the equations. To allow concurrent use of an arbitrary number of operators and to simplify inter-module connections (both within ...

Applied digital signal processing systems for vortex flowmeter with digital signal processing

Review of Scientific Instruments, 2009
The spectral analysis is combined with digital filter to process the vortex sensor signal for reducing the effect of disturbance at low frequency from pipe vibrations and increasing the turndown ratio. Using digital signal processing chip, two kinds of digital signal processing systems are developed to implement these algorithms.

Digital signal processing for doppler radar signals

ICASSP '79. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
In a pulsed-doppler radar system the return signal is naturally viewed as a sequence of samples of one or more complex sinusoids plus noise. We have studied several digital processing techniques for estimating a short-time spectral representation of such signals as well as digital techniques for estimating the frequency of a single dominant spectral ...

Orthogonal transforms for digital signal processing

ICASSP '76. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1975
A tutorial-review paper on discrete orthogonal transforms and their applications in digital signal and image (both monochrome and color) processing is presented. Various transforms such as discrete Fourier, discrete cosine, Walsh-Hadamard, slant, Haar, discrete linear basis, Hadamard-Haar, rapid, lower triangular, generalized Haar, slant Haar and ...

Digital Processing of Biological Signals

IFAC Proceedings Volumes, 1982
Abstract We discuss the motivations and purposes of signal processing of biomedical signals with a view to seeing the various processes in perspective. The two key classes of question are: "what are we trying to do?" and "what processing is appropriate?". A brief discussion is given of the various transformations or models of signals that are used to
