From the Publisher:
This is undoubtedly the most accessible book on digital signal processing (DSP) available to the beginner. Using intuitive explanations and well-chosen examples, this book gives you the tools to develop a fundamental understanding of DSP theory. The author covers the essential mathematics by explaining the meaning and significance of the key DSP equations. Comprehensive in scope, and gentle in approach, the book will help you achieve a thorough grasp of the basics and move gradually to more sophisticated DSP concepts and applications.read more

The teaching and learning of DSP enabled Software Defined Radio using MATLAB & Simulink and the RTL-SDR
Robert Stewart,Louise H. Crockett,D. S. W. Atkinson,Kenneth W. Barlee,E. Sozer,Mike McLernon,N. MacEwen +6 more
TL;DR: The RTL-SDR can be used to acquire and sample RF (radio frequency) signals transmitted in the frequency range 25MHz to 1.75GHz, and the MATLAB and Simulink environment can be employed to develop receivers using first principles DSP (digital signal processing) algorithms as discussed by the authors.

Learning strides in convolutional neural networks
TL;DR: The first downsampling layer with learnable strides, DiffStride, which learns the size of a cropping mask in the Fourier domain, that effectively performs resizing in a differentiable way and allows trading off accuracy for efficiency on ImageNet.

Using vehicle–bridge contact spectra and residue to scan bridge's modal properties with vehicle frequencies and road roughness eliminated
TL;DR: In this paper , the effect of vehicle frequencies is removed by using the vehicle-bridge contact (point) responses and road roughness by the residue of the front and rear contact responses of the two-axle test vehicle.
Designing Digital Filters
TL;DR: Digital Filter Design program presents method to compare desired and designed digital filters by minimizing sum-square error of differences in magnitude and phase angles.

Nouvelle méthode de traitement des potentiels évoqués visuels pour l’estimation de l’acuité visuelle chez le jeune enfant
TL;DR: In this paper, a nouvelle methode de traitement dusignal is presented, which prend en compte les variations de phase, basee sur the transformee en ondelettes discrete stationnaire (TODS) for debruiter le signal and sur le filtre de Kalman etendu (FKE) for l’estimer the reponse du systeme visuel.

Capacity Limits of Optical Fiber Networks
TL;DR: In this article, the capacity limit of fiber-optic communication systems (or fiber channels?) is estimated based on information theory and the relationship between the commonly used signal to noise ratio and the optical signal-to-noise ratio is discussed.

Computing the discrete-time "analytic" signal via FFT
TL;DR: Starting with a real-valued N-point discrete-time signal, frequency-domain algorithms are provided for computing the complex-valued standard N- point discrete time 'analytic' signal of the same sample rate.

Hilbert transform in vibration analysis
TL;DR: In this article, a tutorial on Hilbert transform applications to mechanical vibration is presented, with a large number of examples devoted to illustrating key concepts on actual mechanical signals and demonstrating how the Hilbert transform can be taken advantage of in machine diagnostics, identification of mechanical systems and decomposition of signal components.

Event-Related EEG Time-Frequency Analysis : An Overview of Measures and An Analysis of Early Gamma Band Phase Locking in Schizophrenia
TL;DR: The finding suggests that the early-evoked gamma band response to auditory stimuli is deficiently synchronized in schizophrenia, and is to be reconciled with prior studies that failed to find this effect.
