本书分成三部分，第一部分讨论了仿真的作用和方法论。第二部分介绍了采样定理，滤波器模型、锁相环等的仿真。第三部分是高层建模与仿真方法。-The book is divided into three parts, the first section discusses the role of simulation and methodology. The second part of the sampling theorem, the filter model, phase-locked loop simulation and so on. The third part is high-level modeling and simulation methods.
