A digital filter can be pictured as a "black box" that accepts a sequence of numbers and emits a new sequence of numbers. In digital audio signal processing applications, such number sequences usually represent sounds. For example, digital filters are used to implement graphic equalizers and other digital audio effects. This book is a gentle introduction to digital filters, including mathematical theory, illustrative examples, some audio applications, and useful software starting points. The theory treatment begins at the high-school level, and covers fundamental concepts in linear systems theory and digital filter analysis. Various "small" digital filters are analyzed as examples, particularly those commonly used in audio applications. Matlab programming examples are emphasized for illustrating the use and development of digital filters in practice.

Handbook of Filter Synthesis, originally published in 1967 is the classic reference for continuous time filter design. The plots of filter behaviour for different designs, such as ripple and group delay, make this book invaluable. The discussion of how to synthesize a bandpass, bandpass, or bandstop filter from a lowpass prototype is also very useful.

There has been much concern over the impact of partisan echo chambers and filter bubbles on public debate. Is this concern justified, or is it distracting us from more serious issues? Axel Bruns argues that the influence of echo chambers and filter bubbles has been severely overstated, and results from a broader moral panic about the role of online and social media in society. Our focus on these concepts, and the widespread tendency to blame platforms and their algorithms for political disruptions, obscure far more serious issues pertaining to the rise of populism and hyperpolarisation in democracies. Evaluating the evidence for and against echo chambers and filter bubbles, Bruns offers a persuasive argument for why we should shift our focus to more important problems. This timely book is essential reading for students and scholars, as well as anyone concerned about challenges to public debate and the democratic process.

“A book about a rare life, profound love, profound grief, anxiety, self-assurance, empowerment, aging, loss, and joy. It is nuanced, complex, insightful, helpful, and constantly surprising.” —Ann Patchett, New York Times bestselling author of These Precious Days Writer and former model Paulina Porizkova pens a series of intimate, introspective, and enlightening essays about the complexities of womanhood at every age, pulling back the glossy magazine cover and writing from the heart. Born in Cold War Czechoslovakia, Paulina Porizkova rose to prominence as a model, appearing on her first Sports Illustrated Swimsuit Issue cover in 1984. As the face of Estée Lauder in 1989, she was one of the highest-paid models in the world. When she was cast in the music video for the song “Drive” by The Cars, it was love at first sight for her and frontman Ric Ocasek. He was forty at the time, and Porizkova was nineteen. The decades to come would bring marriage, motherhood, a budding writing career; and later sadness, loneliness, isolation, and eventually divorce. Following her ex-husband’s death—and the revelation of a deep betrayal—Porizkova stunned fans with her fierce vulnerability and disarming honesty as she let the whole world share in her experience of being a woman who must start over. This is a wise and compelling exploration of heartbreak, grief, beauty, aging, relationships, re-invention and finding your purpose. In these essays, Porizkova bares her soul and shares the lessons she’s learned—often the hard way. After a lifetime of being looked at, she is ready to be heard.

Upon its initial publication, The Circuits and Filters Handbook broke new ground. It quickly became the resource for comprehensive coverage of issues and practical information that can be put to immediate use. Not content to rest on his laurels, in addition to updating the second edition, editor Wai-Kai Chen divided it into tightly-focused texts that made the information easily accessible and digestible. These texts have been revised, updated, and expanded so that they continue to provide solid coverage of standard practices and enlightened perspectives on new and emerging techniques. Passive, Active, and Digital Filters provides an introduction to the characteristics of analog filters and a review of the design process and the tasks that need to be undertaken to translate a set of filter specifications into a working prototype. Highlights include discussions of the passive cascade synthesis and the synthesis of LCM and RC one-port networks; a summary of two-port synthesis by ladder development; a comparison of the cascade approach, the multiple-loop feedback topology, and ladder simulations; an examination of four types of finite wordlength effects; and coverage of methods for designing two-dimensional finite-extent impulse response (FIR) discrete-time filters. The book includes coverage of the basic building blocks involved in low- and high-order filters, limitations and practical design considerations, and a brief discussion of low-voltage circuit design. Revised Chapters: Sensitivity and Selectivity Switched-Capacitor Filters FIR Filters IIR Filters VLSI Implementation of Digital Filters Two-Dimensional FIR Filters Additional Chapters: 1-D Multirate Filter Banks Directional Filter Banks Nonlinear Filtering Using Statistical Signal Models Nonlinear Filtering for Image Denoising Video Demosaicking Filters This volume will undoubtedly take its place as the engineer's first choice in looking for solutions to problems encountered when designing filters.
