2 unusual facts about Signal Processing


Guido Schuster

Guido M. Schuster is a Professor of Electrical and Computer Engineering at the Hochschule für Technik Rapperswil (HSR), Rapperswil, St. Gallen, Switzerland, where he focuses on digital signal processing and wireless sensor networks.

Signal processing

According to Alan V. Oppenheim and Ronald W. Schafer, the principles of signal processing can be found in the classical numerical analysis techniques of the 17th century.


Bandwidth expansion

Bandwidth expansion is a technique for widening the bandwidth or the resonances in an LPC filter.

Control track

The control track encodes a series of pulses, each pulse corresponding to the beginning of each frame.

Fredric J. Harris (or, as he prefers to spell his name, fred harris) is a professor of Electrical engineering and CUBIC signal processing chair at San Diego State University and an internationally renowned expert on DSP and Communication Systems.

John A. Westlake

He has also been working with semiconductor companies that patent some of his technologies: UK patent on Feedback controller for PWM amplifier, International patent on a signal processing circuit.

Mathematics of Control, Signals, and Systems

Mathematics of Control, Signals, and Systems is a peer-reviewed scientific journal that covers research concerned with mathematically rigorous system theoretic aspects of control and signal processing.

Multitaper

In signal processing, the multitaper method is a technique developed by David J. Thomson to estimate the power spectrum SX of a stationary ergodic finite-variance random process X, given a finite contiguous realization of X as data.

Patrick N. Keating

Patrick N. Keating is a theoretical physicist who has contributed to several fields of solid-state physics, including semiconductors, semi-insulators and the basic properties of solid materials, and to other fields including optics, liquid crystals, acoustic holography, and signal processing.

Sanjeev Kulkarni

Sanjeev Ramesh Kulkarni (born Mumbai, India, September 21, 1963) is Professor of Electrical Engineering at Princeton University, where he teaches and conducts research in a broad range of areas including statistical inference, pattern recognition, machine learning, information theory, and signal/image processing.

Sine and cosine transforms

They are the forms originally used by Joseph Fourier and are still preferred in some applications, such as signal processing or statistics.

Stéphane Mallat

Specifically, he collaborated with Yves Meyer to develop the Multiresolution Analysis (MRA) construction for compactly supported wavelets, which made the implementation of wavelets practical for engineering applications by demonstrating the equivalence of wavelet bases and conjugate mirror filters used in discrete, multirate filter banks in signal processing.
