Signals and Systems

Theory and Applications

Michigan Publishing Services, 2018

[From the Preface] This is a signals and systems textbook with a difference: Engineering applications of signals and systems are integrated into the presentation as equal partners with concepts and mathematical models, instead of just presenting the concepts and models and leaving the student to wonder how it all relates to engineering.

The first six chapters of this textbook cover the usual basic concepts of continuous-time signals and systems, including the Laplace and Fourier transforms. Chapters 7 and 8 present the discrete-time version of Chapters 1–6, emphasizing the similarities and analogies, and often using continuous-time results to derive discrete-time results. The two chapters serve to introduce the reader to the world of discrete-time signals and systems. Concepts highlighted in Chapters 1–8 include: compensator feedback configuration (Ch. 4); energy spectral density, group delay, expanded coverage of exponential Fourier series (Ch. 5); filtering of images, Hilbert transform, single-sideband (SSB), zero and first-order hold interpolation (Ch. 6); the Cooley-Tukey FFT (Ch. 7); bilateral z-transform and use for non-minimum-phase deconvolution (Ch. 8). Chapter 9 covers the usual concepts of discrete-time signal processing, including data windows, FIR and IIR filter design, multirate signal processing, and auto-correlation and crosscorrelation. It also includes some nontraditional concepts, including spectrograms, application of multirate signal processing, and the musical circle of fifths to audio signal processing, and some biomedical applications of autocorrelation and cross-correlation. Chapter 10 covers image processing, discrete-time wavelets (including the Smith-Barnwell condition and the Haar and Daubechies discrete-time wavelet expansions), and an introduction to compressed sensing. This is the first sophomore-junior level textbook the authors are aware of that allows students to apply compressed sensing concepts. Applications include: image denoising using 2-D filtering; image denoising using thresholding and shrinkage of image wavelet transforms; image deconvolution using Wiener filters; “valid” image deconvolution using ISTA; image inpainting; tomography and the projection-slice theorem, and image reconstruction from partial knowledge of 2-D DFT values. Problems allow students to apply these techniques to actual images and learn by doing, not by only reading.

Signals of Being, or Verbum Caro Factum Est

A Play in Three Acts

Volodymyr Rafeyenko

Harvard University Press, 2025

In the early days of Russia’s 2022 invasion of Ukraine, the residents of a small co-op community outside of Kyiv find themselves in increasingly desperate circumstances, surrounded by occupying Russian forces. Pinched between Bucha and Borodianka, cut off from aid, and unable to escape, their attempts at survival rely on connection: a cellphone signal in the forest, their bonds with each other, and, ultimately, new understandings of what it means to be Ukrainian. Weaving Shakespeare with both Ukrainian literary classics and contemporary works, Volodymyr Rafeyenko’s Signals of Being stages a captivating dramatic interpretation of a country at war.

Signs and Signals from Vietnam

Essays on Contemporary Art

Edited by Pamela N. Corey, Nora A. Taylor, and Ðo Tuong Linh

National University of Singapore Press, 2026

The first English-language volume on Vietnamese contemporary art.

Contemporary art in Vietnam is a dynamic field shaped by memory, history, and experimentation. Over the last thirty years, Vietnamese artists have come to command international recognition, even as a growing domestic market for contemporary art fosters alternative infrastructures of collection and exhibition. Signs and Signals from Vietnam brings together artists, curators, and academics to examine artistic practice and contemporary art histories in Vietnam today.

Moving beyond familiar North-South or diasporic-national divides, the essays represent the perspectives of Vietnamese, Vietnamese diasporic, and non-Vietnamese writers of different generations, affiliations, and positionalities. Contributors trace the inventive ways artists work with language, narrative, performance, and archival practice to communicate through their art. Key themes running through the volume represent the predominant concerns of Vietnamese artists over the past three decades, including the enduring impact of socialist paradigms in contemporary art, gender, diaspora, memory, and the environment. Together, these essays demonstrate how contemporary art can convey lesser-known histories, contested narratives, and personal perspectives.
