在他的基础上,我帮他补充一下  呵呵。。。。。。。。希望斑竹不要删帖啊!!!!!

这本书是关于Frequency Acquisition的,同时书中也对锁相环模块做了详细的分析。作者给出了大量的仿真实例,适当的减少理论分析和数学推导。特别适合工程应用,不被数学公式所累,且书中将仿真实例的例程也放在网上(书中提供有网址),方便大家学习和参考。

下面这段是摘自书中的Preface部分的内容!!!!   从红色字体看出  这本书跟已有的书区别还是蛮大的。

Many excellent treatises covering phase-locked loops (PLLs) have been published, but to the author’s surprise, few books exist covering the frequency acquisition assistance techniques necessary and/or available. A PLL by itself cannot become useful until it has acquired the applied signal’s frequency. This acquisition process has been treated with extreme mathematical and/or graphical rigor in the past, mainly by Viterbi and Jet Propulsion Lab (JPL) in publications featuring phase-plane trajectories. However, most of the PLL circuits in other analyses had no explicit assistive circuitry included. Often, a PLL will never reach frequency acquisition (called “capture” in most texts) by itself without explicit assistive circuits (with exception of the overused phase/frequency detector-based approach that has performance drawbacks during settled closed-loop operation that will be identified and explained later in detail).


This book attempts to bridge this information gap. Since mathematical rigor for its own sake can degenerate to intellectual “rigor mortis,” the author hopes to offer a treatment of the subject that can be comprehended by both engineer and technician (except for an occasional formula that might be included for essential reasons and even then the book is organized so that the nonmathematician can skip it and move on to the essence of the thought being discussed). A more important reason exists for avoiding excessive mathematical verbosity: often the objective gets forgotten and lost in the minutia; assumptions are too confining or too optimistic or too pessimistic, and the motive behind the complexity is not well stated. For this reason, we have decided to focus on the practical and to simulate actual situations wherever possible, both for clarity, so that the reader can take an active role in altering the assumptions and qualifications of a certain architecture and then rerun the simulation to see what his or her results might be. It is disappointing to be shown a solution that does not fit the problem.
