The new digital broadcast system family is very different from existing conventional broadcast systems. It is standardised in a large number of documents (from ITU-R, ISO/IEC, ETSI, EBU, and others) which are often difficult to read. This book offers a comprehensive and fully updated overview of Digital Audio Broadcasting (DAB, DAB+) and Digital Multimedia Broadcasting (DMB), and related services and applications. Furthermore, the authors continue to build upon the topics of the previous editions, including audio coding, data services, receiver techniques, frequencies, and many others. There are several new sections in the book, which would be otherwise difficult to locate from various sources.

Key Features:

This book will be of interest to planning and system engineers, developers for professional and domestic equipment manufacturers, service providers, postgraduate students and lecturers in communications technology. Broadcasting engineers in related fields will also find this book insightful.

Die Funktechnik ermöglicht die Ausweitung der astronomischen Beobachtungen über das Licht hinaus auf andere Frequenzbereiche. Dies führte zur Entdeckung zahlreicher kosmischer Radioquellen, deren physikalische Ursachen erläutert werden, ebenso die Funktionsweise eines Radioteleskops. Schon mit kleinen Radioteleskopen kann die Strahlung der Sonne und anderer Radioquellen sowie die 21-cm-Strahlung aus der Milchstraße beobachtet werden. Durch Interferometrie kann eine wesentlich höhere Auflösung als mit einzelnen Radioteleskopen erzielt werden. Dadurch kann die radioastronomische Forschung zu vielen aktuellen Fragen der Astronomie, Kosmologie und Physik beitragen.

Radio technology enables the extension of astronomical observations beyond light to other frequency ranges. This has led to the discovery of numerous cosmic radio sources, the physical causes of which are explained as well as how a radio telescope works. Even small radio telescopes can observe radiation from the Sun and other radio sources, as well as the 21-cm radiation from the Milky Way. Through interferometry, much higher resolution can be achieved than with individual radio telescopes. As a result, radio astronomical research can contribute to many current questions in astronomy, cosmology, and physics.
