"Collins...helps systems engineers, designers, and managers in TV broadcasting make a smooth transition from analog to digital technologies." (SciTech Book News Vol. 25, No. 2 June 2001) Informationen zum Autor Dr. Liam Collins is the executive director of the Madison Policy Forum, a senior fellow with New America, and a permanent member with the Council on Foreign Relations. Colonel (retired) Collins served in the US Army for 27 years. As a career Special Forces officer, he conducted multiple operational and combat deployments to Afghanistan, Iraq, Bosnia, South America, and the Horn of Africa. In Iraq, Liam conducted operations in Baghdad, Fallujah, Ramadi, and many other cities. Liam retired from the military in 2019 as the founding director of the Modern War Institute and the director of the Department of Military Instruction at the United States Military Academy at West Point. He holds a Bachelor of Science degree in Mechanical Engineering (Aerospace) from the United States Military Academy, and a Master's in Public Affairs and a PhD from Princeton University's School of Public and International Affairs. Klappentext What today's TV engineers need to know about working with digital systems This book helps systems engineers, designers, and managers in TV broadcasting make a smooth transition from analog to digital technologies. With an emphasis on RF transmission rather than baseband signal processing, it offers in a single resource a complete discussion of the digital TV signal, from the input to the transmitter to the output of the receiving antenna. Industry expert Gerald Collins provides clear, up-to-date explanations that build upon experience engineers already have with analog technology, including comparisons between analog and digital systems, factors affecting the performance of VHF and UHF stations, and down-to-earth discussions of modern high-power RF filters. Plus, he provides over 150 high-quality illustrations and tables as well as extensive references for readers wishing to pursue the subject more in depth. The discussion includes: * Major digital TV transmission standards * Key performance parameters of interest to RF engineers * The theory of operation and practical implementation of major system components * Factors affecting propagation of digital TV signals * Results of field testing of DTV systems * Performance data on the American ATSC, the European DVB, and the Japanese ISDB-T systems The DTV waveform shown on the cover was photographed by Bob Plonka of Harris Corporation and is used with permission. Zusammenfassung The switch from analogue to digital broadcast systems is a hot topic in broadcast engineering as the technology rapidly evolves. This text discusses both American ATSC and European DVT-T systems, and collates the latest research previously scattered throughout various journals.
