【内容简介】

　　《数字信号处理实践方法（第二版）》根据实际工程应用和具体实例，详细介绍了数字信号处理（DSP）领域内的基本概念和相关技术。全书共分为14章，首先讲解了DSP的基本概念及其应用，并从实际的例子出发，阐述了DSP的一些基本内容，如信号的抽样、量化及其在实时DSP上的内涵。然后，作者介绍了离散变换（DFT和FFT），离散时间信号与系统分析的工具（z变换），以及DSP的基本运算（相关和卷积），并分析了数字滤波器设计的实际问题。《数字信号处理实践方法（第二版）》还介绍了多抽样率数字信号处理、自适应数字滤波器、谱估计及其分析等现代数字信号处理理论，最后讨论了通用和专用数字信号处理器、定点DSP系统有限字长效应分析及DSP的应用和设计实例。另外，书中还提供了有关范例和实验的MATLAB实现方法。
　　《数字信号处理实践方法（第二版）》可作为通信与电子信息类专业高年级本科生和研究生的教材或教学参考书，而且对于相关学科的工程技术人员也具有很好的参考价值。
