TLDR
In this paper, the authors provide a thorough treatment of the fundamental theorems and properties of discrete-time linear systems, filtering, sampling, and discrete time Fourier analysis.Abstract:
For senior/graduate-level courses in Discrete-Time Signal Processing. THE definitive, authoritative text on DSP -- ideal for those with an introductory-level knowledge of signals and systems. Written by prominent, DSP pioneers, it provides thorough treatment of the fundamental theorems and properties of discrete-time linear systems, filtering, sampling, and discrete-time Fourier Analysis. By focusing on the general and universal concepts in discrete-time signal processing, it remains vital and relevant to the new challenges arising in the field --without limiting itself to specific technologies with relatively short life spans.read more

TL;DR: It is shown that adolescents with ASD versus controls have weaker connectivity between the posterior hub of the default network and the right superior frontal gyrus, and this findings indicate that SOM is a complementary method for calculating connectivity in a clinical population.

A new perceptually motivated MVDR-based acoustic front-end (PMVDR) for robust automatic speech recognition
TL;DR: A novel feature extraction algorithm, perceptual-MVDR (PMVDR), which computes cepstral coefficients from the speech signal is proposed, shown to better model the speech spectrum compared to traditional feature extraction approaches.

A dynamic elastic model for segmentation and tracking of the heart in MR image sequences
TL;DR: This paper proposes an algorithm to solve the continuous dynamical problem associated to numerically adapting the model to the image sequence and presents a novel dynamic model, based on the equation of dynamics for elastic materials and on Fourier filtering.

Toward a taxonomy of attention shifting: individual differences in fMRI during multiple shift types.
TL;DR: A model of cognitive-emotional interaction in attention shifting is discussed, in which reward-related signals in the VMPFC guide efficient selection of tasks in the lateral prefrontal and parietal cortices.

TL;DR: This paper establishes the exact relationship between the continuous and the discrete phase difference of two shifted images, and shows that their discretephase difference is a two-dimensional sawtooth signal.
