This textbook introduces the transmission of digital signals over disturbed channels, emphasizing an intuitive and mathematically grounded explanation of baseband transmission. It recaps essential fundamentals of signal and system theory and explores functional interdependencies in baseband transmission to advance the understanding of baseband transmission concepts. The wired transmission using copper cable is highlighted as an important transmission technique. The copper cable’s transmission characteristics are described using classical electrical engineering and system theory methods. Baseband techniques are applied to the transmission over the linearly distorting channel copper cable, with discussions on filtering and equalization. The textbook includes detailed derivations, numerical examples, solved exercises and various illustrations.

Dieses Lehrbuch ist eine einführende Darstellung der Übertragung digitaler Signale über gestörte Kanäle. Schwerpunkt ist die physikalisch-anschauliche und zugleich mathematisch-fundierte Erklärung der Übertragung im Basisband. Dazu werden notwendige Grundlagen der Signal- und Systemtheorie rekapituliert und funktionale Abhängigkeiten bei der Basisbandübertragung herausgearbeitet, um ein Verständnis der grundlegenden Probleme bei der Nachrichtenübertragung zu ermöglichen. Als wichtiger Übertragungskanal wird das Kupferkabel betrachtet und seine übertragungstechnischen Eigenschaften werden mit klassischen elektrotechnischen und systemtheoretischen Methoden beschrieben. Die zuvor beschriebenen Basisbandverfahren werden zur Übertragung über den linear verzerrenden Kanal eines Kupferkabels angewendet und Möglichkeiten der Filterung und Entzerrung erläutert. Dem einführenden Charakter des Lehrbuches entsprechend werden jeweils ausführliche Herleitungen angegeben sowie numerische Beispiele und eine Vielzahl von Abbildungen verwendet.

Intervals of high-activity alternating with long low-activity periods can be found in many areas of daily life, with researchers coining the phenomenon as bursts. As burstiness has become prevalent in many fields, understanding it and knowing how to manage it are crucial in order to be able to get all the benefits associated with it. Burstiness Management for Smart, Sustainable and Inclusive Growth: Emerging Research and Opportunities provides innovative insights into burstiness’s role in decision-making in business and its function as a predictor of performance. The content within this publication covers topics such as burstiness in business and e-business applications, as well as consumer behavior and sustainable development. It is a vital reference source for business managers, business professionals, academicians, researchers, and graduate-level students interested in understanding how burstiness and its consequences are processed in diverse and dynamic environments.

Substitution of hazardous substances is a prioritised objective in chemical regulation and risk management. However, it is experienced as a tough task with often inconsistent results. Based on thirteen case studies, this book analyzes substitution as an innovation process and attempts to give answers to the following questions: Why and under which circumstances are companies able and willing to substitute hazardous substances? What are the main drivers and the main barriers? In which way can communication along the supply chain support environmental innovation? How can risk management appropriately deal with the lack of knowledge, with uncertainties and incomplete knowledge about the possible effects of different substances? Recommendations for action are provided for commercial and state institutions and consumers and thus for all actors engaged in the European reform of chemicals policy following the REACH system.
