莱昂斯（Richard G．Lyons），毕业于美国加州阿克隆大学，曾任国家安全局和TRW（天合）汽车集团公司众多DSP系统的首席硬件工程师，负责系统设计、开发、测试和安装。曾任教于加利福尼亚大学圣塔克鲁兹分校，并发表过很多有关DSP的文章。作为IEEE Signal Processing Magazine的副主编，开设了DSP Tips＆Tricks专栏并负责编辑。
《数字信号处理（第2版）（英文版）》在Richard G. Lyons所著Understanding Digital Signal Processing ， Second。Edition的基础上进行了改编，针对通信类学校本科教学大纲，删除了教学中一般不涉及的内容，调整了章节顺序，并增加了z反变换、滤波器结构、线性相位FIR滤波器及其结构、模拟滤波器简介的内容，使教材内容更加完整。全书在概述了离散序列和系统的定义和实例之后，详细讨论了离散系统的特性、信号的离散化和离散卷积、z变换、离散时间傅里叶变换和离散傅里叶变换、快速傅里叶变换、数字滤波器结构以及有限和无限脉冲响应数字滤波器的设计等基本概念和基本理论。书中涉及的数学知识以简明形式给出，深入浅出，易于理解。《数字信号处理（第2版）（英文版）》每章都增加了例题、习题和MATLAB例题，以便加强对每章内容的理解和掌握。
《数字信号处理（第2版）（英文版）》可作为理工类大专院校电子、计算机、通信等专业的本科生双语教学教材，对于DSF，领域的工程技术人员也有很好的参考价值。
