本书选材以数字信号处理的基础内容为主,同时也给出了现代信号处理部分内容。书中以主要篇幅讨论离散信号和离散系统的基本概念及其时域分析、变换域分析、数字滤波器的结构域设计、有限字长分析及随机信号的基本概念等。这是数字信号处理中的经典内容,也是进一步学习和掌握更多信号处理理论的基础。此外,本书讨论了多抽样率信号处理问题,其中的滤波器组(Filter Bank)是近十年来非常活跃的内容,广泛应用于带编码和小波变换。本书*后一章介绍数字信号处理的应用,并讨论现代谱估计的部分内容。 本书具有丰富的例题、习题以及基于Matlab的信号处理算法的程序。 本书非常适合电类专业高年级本科生用作教材,也可作为研究生的参考资料和工程技术人员的自学用书。
