This book is certainly worth owning. It is 1 of 7 PLL books that I own. I use it as a reference for the basic PLL linearized transfer functions even after I found that the transfer function for the 2nd order PLL with ideal integrator is incorrect.

Best covers analog PLLs with each block replaced by a digital implementation based on the incremental improvements made in standard TTL implementations of PLLs offered over the decades. This allows the reader to fully understand each digital block and the PLL in a way that is excellent for an introductory text.

The digital PLL is a numerical implementation of each PLL function, which has by definition an analog function. One way to implement such a numerical PLL is via replacing each analog function with the equivalent numerical function, without much focus on the Z domain and digital signal processing (DSP) concepts. That is what this book does. Look elsewhere for a book with heavy use of Z domain math (consider the Kluwer Acedemic Press Book 'Phase-Locked Loops for Wireless Communications: Analog and Digital' by Stephen (?) for more DSP math.

Best's approach is viable. I have personally designed a leading edge all-digital PLL, adding patent pending analog enhancements, and can asure the reader that straight-forward DSP approaches do not lead to the optimal designs, at least at the high data rates. Understanding of the PLL in analog form, and then adding the digital analogues is an excellent way to go. Best's book is surprisingly very different from Wolaver's book, almost orthogonal; start with Wolaver, then add Best if adding digital gates step by step to an analog PLL is of interest to you (it was to me).

I think this book give designers a good understanding of the fundamental theorie of PLLs. It gives you step by step the necessarly mathematical background to understand how a PLL is working. The examples are mostly for analog PLLs, but the mathematical theories are the same for all kind of implementations.

I really like the chapter where the different PLL-Parameters are defined: It clearly explains and defines the different working modes like "hold", "lock" or "pull-in".

The book is not for people who are looking for prepared applications. Even when the subtitle of the book suggests this.

This book provides explanations of PLL behavior with an easy to understand methodology that includes analogies of PLLs to mechanical systems. He covers analog, digital, all digital, and software PLLs. He has a good explaination of all digital PLLs and is one of the few books that has a practical chapter on making measurements on a PLL. A computer simulation program is provided that helps readers look at PLL performance. The only issue with this book is that it does not cover transistor level components so that IC engineers can design a PLL.

This book is generally good although I have not read all of the book yet.
It approaches at the system level of the PLL, not at the circuit level, so reader may need another book if they have to design the PLL.

The book is most helpful, but a little out of date with regards to moderm PLL techniques, especialy charge pump o/p types and makes no referance to lead lag passive filter loops. This hinders the usefulness of the enclosed program which would benefit from a 'modernisation'
