The design and application of phase-locked loops is one of the most sophisticated - and significant - aspects of modern electronics. For many years, Phase-Locked Loops had been the standard reference for those who create and apply the vital components that lock in frequencies used for an ever-lengthening list of applications. Now this new edition goes a step beyond, becoming the first and only book on PLLs to include simulation software and to bring you the newest information on digital and integrated circuit design.
