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.

A Comparison of the Squared Energy and Teager-Kaiser Operators for Short-Term Energy Estimation in Additive Noise

TL;DR: The short- and medium-term properties of the mean squared amplitude and Teager-Kaiser energy approaches are focused on, as well as, on their performance in the presence of additive noise.

A review of glottal waveform analysis

TL;DR: Glottal inverse filtering is of potential use in a wide range of speech processing applications as the process of voice production is, to a first order approximation, a source-filter process, then obtaining source and filter components provides for a flexible representation of the speech signal for use in processing applications.

In Situ Additive Manufacturing Process Monitoring With an Acoustic Technique: Clustering Performance Evaluation Using K-Means Algorithm

TL;DR: In this article, acoustic signatures were used for in situ monitoring of the metal direct energy deposition (DED) AM process operating under different process conditions, and a new approach of K-means statistical clustering algorithm was used for the classification of different process condition, and quantitative evaluation of the classification performance in terms of cohesion and isolation of the clusters.

A dorsiventral leaf radiative transfer model: Development, validation and improved model inversion techniques

TL;DR: In this article, a Dorsiventral Leaf Model (DLM) is presented to simulate leaf radiative transfer, which is conceived as a plate model with a stochastic distribution of different groups of layers and is modeled by assigning non-uniform distributions of pigments, water and dry matter to palisade and mesophyll layers.

Two Channel Data Acquisition System for Heart Sound Segmentation Algorithm Based on Instantaneous Energy of Electrocardiogram

M Najeb, +1 more
TL;DR: The algorithm utilizes instantaneous energy of electrocardiogram (ECG) to estimate the presence of S1 and S2 and thus, heart sound segmentation can be done as it is essential in the automatic diagnosis of heart sounds.
