Cable TV systems have transported analog signals for decades, but now they're rapidly transitioning to a digital environment -- where yesterday's rules and tools for testing and measurement may no longer apply. This authoritative guide shows CATV professionals how to make the transition, implementing digital services that deliver maximum quality and reliability.KEY TOPICS:Understand the fundamental nature of digital signals, data communications and digital signal transportation -- and how these compare to the analog environments you're used to. Learn the most important, widely-used digital measurement techniques, including setting relative analog and digital signal power levels using a spectrum analyzer. Master key digital signal composition features, such as adaptive equalization, error correction and compression; and understand the strengths and weaknesses of multiplexing techniques and digital modulation formats. No matter how complex or simple your digital services will be, this book will help you get results faster, use your equipment more effectively, and build better systems.MARKET:All CATV professionals involved in designing, implementing, testing and configuring digital systems.
