Digital Signal Processing
The Digital Signal Processing Group develops signal processing algorithms that span a wide variety of application areas including speech and image processing, sensor networks, communications, radar and sonar, and the approach to new algorithms includes some unconventional directions.
Introduction to Digital Speech Processing
A comprehensive overview of digital speech processing that ranges from the basic nature of the speech signal, through a variety of methods of representing speech in digital form, to applications in voice communication and automatic synthesis and recognition of speech.

This article reviewed the definition and properties of S-G filters and showed how they can be designed easily using polynomial approximation of an impulse sequence, and focused on the frequency domain properties.
The chirp z-transform algorithm
A computational algorithm for numerically evaluating the z -transform of a sequence of N samples is discussed, based on the fact that the values of the z-transform on a circular or spiral contour can be expressed as a discrete convolution.
Morphological filters-Part I: Their set-theoretic analysis and relations to linear shift-invariant filters
The representation of classical linear filters in terms of morphological correlations, which involve supremum/infimum operations and additions, are introduced and demonstrate the power of mathematical morphology as a unifying approach to both linear and nonlinear signal-shaping strategies.
Morphological skeleton representation and coding of binary images
The morphological skeleton is shown to unify many previous approaches to skeletonization, and some of its theoretical properties are investigated.
Nonlinear filtering of multiplied and convolved signals
An approach to some nonlinear filtering problems through a generalized notion of superposition has proven useful. In this paper this approach is investigated for the nonlinear filtering of signals…
