In real electronic systems, voltage and current signals are not necessarily of a periodical quantity, due to the presence of nonharmonic components or/and possible stochastic variation. This book presents in four chapters methods for analyzing and processing and reconstructing complex signals. The processing of nonharmonic components of ac signals, i.e. interharmonics and subharmonics based on the principles of synchronous sampling is a topic of chapter two. The conditions, required for the performance of such a processing, have necessarily been derived. The problem of the reconstruction of complex periodic signals, which is in the focus of chapter three of this monograph, has been given special attention. A completely new protocol, which enables the development of much superior and more efficacious algorithms, has been developed, and the obtained results are unique in global practice. A newly developed method for the calculation of basic parameters of the processed voltage and current signals is given in chapter four. Having being practically verified, this method has demonstrated exceptionally favorable performance. The monograph is beneficial to specialists and experts involved in problems of this scientific field, and it will serve as a useful guideline to follow in further investigations.

Microphone arrays have attracted a lot of interest over the last few decades since they have the potential to solve many important problems such as noise reduction/speech enhancement, source separation, dereverberation, spatial sound recording, and source localization/tracking, to name a few. However, the design and implementation of microphone arrays with beamforming algorithms is not a trivial task when it comes to processing broadband signals such as speech. Indeed, in most sensor arrangements, the beamformer tends to have a frequency-dependent response. One exception, perhaps, is the family of differential microphone arrays (DMAs) that have the promise to form frequency-independent responses. Moreover, they have the potential to attain high directional gains with small and compact apertures. As a result, this type of microphone arrays has drawn much research and development attention recently. This book is intended to provide a systematic study of DMAs from a signal processing perspective. The primary objective is to develop a rigorous but yet simple theory for the design, implementation, and performance analysis of DMAs.

Handbook of Signal Processing Systems is organized in four parts. The first part motivates representative applications that drive and apply state-of-the art methods for design and implementation of signal processing systems; the second part discusses architectures for implementing these applications; the third part focuses on compilers and simulation tools; and the fourth part describes models of computation and their associated design tools and methodologies. This handbook provides: A comprehensive overview of signal processing systems Standalone, complete reference to signal processing systems A comprehensive index for ease of use An extensive bibliography for further reading This handbook is essential for those involved in R&D in the design, architecture, and implementation of a wide array of signal processing systems. This handbook is also suitable as a first point of entry to the field for undergraduate and post-graduate students in engineering, computer sciences, and system engineering.
