Der Band lotet Perspektiven einer rekonstruktiv-sinnverstehenden Forschung für die Untersuchung von Schule und Unterricht im digitalen Wandel aus. Es werden vier empirische Studien vorgestellt und ihre Befunde theoretisch und methodisch eingeordnet. Die Studien interessieren sich für die Veränderungen wie auch die Stabilität von Praktiken im Unterricht, wenn digitale Medien genutzt werden. Und sie untersuchen, wie Schüler:innen und Lehrkräfte die mit der Digitalisierung einhergehenden Transformationsprozesse deuten. Die generierten Forschungsperspektiven werden durch die Diskussion der Erträge der Studien im Hinblick auf zentrale Fragen des digitalen Wandels und seine Erforschung am Ende des Bandes vertiefend konturiert.

Visible light communication (VLC) has drawn much attention recently. Compared to the traditional radio frequency wireless communications (RFWC), VLC has many advantages, such as worldwide availability, high security, large bandwidth, immunity to radio frequency interference, and unlicensed spectrum. Due to its superiority, VLC has become a complementary solution to the overcrowded RFWC. This book intends to introduce the latest research progress in VLC, which covers the novel modulation techniques for VLC, the multiple input multiple output (MIMO) techniques for VLC, the collaborative communication techniques for VLC, and the practical applications of VLC. The book is a useful resource for researchers, engineers, scientists, and students interested in understanding and designing VLC systems.

In many applications, radio frequency (RF) signals need to be transmitted and processed without being digitalized. Optical fiber provides a transmission medium in which RF modulated optical carriers can be transmitted and distributed with very low loss, making it more efficient and less costly than conventional electronic systems. This volume presents a review of RF photonic components, transmission systems, and signal processing examples in optical fibers from leading academic, government, and industry scientists working in this field. It also introduces the reader to various related technologies such as direct modulation of laser sources, external modulation techniques, and detectors. The text is aimed at engineers and scientists engaged in the research and development of optical fibers and analog RF applications. With an emphasis on design, performance and practical application, this book will be of particular interest to those developing systems based on this technology.

This important book deals with the modeling and design of higher-order single-stage delta-sigma modulators. It provides an overview of the architectures, the quantizer models, the design techniques and the implementation issues encountered in the study of the delta-sigma modulators. A number of applications are discussed, with emphasis on use in the design of analog-to-digital converters and in frequency synthesis. The book is education- rather than research-oriented, containing numerical examples and unsolved problems. It is aimed at introducing the final-year undergraduate, the graduate stu
