PhaseLock Techniques 3rd Edition FLOYD
The first edition of this book was published in 1966 and the second in 1979. Phaselock was an unimaginably exotic subject in 1966, with limited applications and few practitioners. Now phaselock is a mature subject: myriads of phaselock loops are ensconced in the world’s electronic devices; numerous applications include phaselock loops; large numbers of practitioners deal with phaselock. No other books on phaselock loops existed when the first edition was published, but more than 20 exist today. Why is a third edition justified at this time? In 1966, a simple, short introduction to the basics of the subject was needed for an audience for whom phaselock was strange and new. Today, phaselock loops are firmly established in the mainstream of electronics engineering. Much new information on phaselock loops has accumulated over the years, and several topics once thought important have proved to be ephemeral. Experience has taught me that certain explanations would be better presented from revised viewpoints. There is no need for another introductory text; that function is well served by a number of the books listed in Section 1.3 and probably others as well. Instead, this book reexamines the traditional phaselock topics in greater depth than previously. In addition, much new material has been included, some of it never before published. Examples of additions include revised and expanded material on transfer functions, two chapters related to phase noise, two chapters related to digital phaselock loops, a chapter on charge-pump phaselock loops, expanded material on phase detectors, and a chapter on anomalous phaselocking.
