Many engineers familiar with analog television broadcast systems are now faced with designing, operating, and maintaining digital television systems. A major reason for this introductory book is to make the transition from analog to digital television broadcasting as painless as possible for these engineers. The emphasis is on radio-frequency (RF) transmission, those elements of the system concernedwith transmitting and propagating the digitally modulated signal. I begin with the digital signal as it emerges from the transport layer and end with the RF signal as it arrives at the receiver. The emphasis is on factors affecting broadcast system performance. The scope of this book is necessarily limited; some topics, such as studioto- transmitter links and receivers are not covered. It is intended as a self-study resource by the broadcast system engineer, as well as a reference for the design engineer, system engineer, and engineering manager. An index is included to make it a more useful resource for future reference. It may be used as a text for a formal training class.
