English | PDF | 1996 | 504 Pages | ISBN : 1441951539 | 28.88 MB

Digital Filters and Signal Processing, Third Edition … with MATLAB Exercises presents a general survey of digital signal processing concepts, design methods, and implementation considerations, with an emphasis on digital filters. It is suitable as a textbook for senior undergraduate or first-year graduate courses in digital signal processing. While mathematically rigorous, the book stresses an intuitive understanding of digital filters and signal processing systems, with numerous realistic and relevant examples. Hence, practicing engineers and scientists will also find the book to be a most useful reference. The Third Edition contains a substantial amount of new material including, in particular, the addition of MATLAB exercises to deepen the students' understanding of basic DSP principles and increase their proficiency in the application of these principles. The use of the exercises is not mandatory, but is highly recommended. Other new features include: normalized frequency utilized in the DTFT, e.g., X(ejomega); new computer generated drawings and MATLAB plots throughout the book; Chapter 6 on sampling the DTFT has been completely rewritten; expanded coverage of Types I-IV linear-phase FIR filters; new material on power and doubly-complementary filters; new section on quadrature-mirror filters and their application in filter banks; new section on the design of maximally-flat FIR filters; new section on roundoff-noise reduction using error feedback; and many new problems added throughout.


数字滤波器与信号处理,第三版……附MATLAB练习题,对数字信号处理的概念、设计方法和实施考虑进行了一般性调查,重点在于数字滤波器。它适合作为数字信号处理的高级本科生或第一年研究生课程教材使用。虽然数学严谨,但本书强调了对数字滤波器及信号处理系统的直观理解,并包含许多现实且相关的例子。因此,实践工程师和科学家也将发现这本书是一本极好的参考书。第三版包含了大量的新内容,特别是添加了MATLAB练习题以加深学生对基本DSP原理的理解并提高他们在这些原则应用中的熟练度。使用练习题并非强制要求,但强烈推荐。其他新特点包括:在DTFT中利用归一化频率,例如X(e^jω);书中各处增加了新的计算机生成插图和MATLAB图表;第六章彻底重写以涵盖采样DTFT;增加对I-IV类线性相位FIR滤波器的覆盖范围;新增关于功率和双互补滤波器的内容;增加一个关于四元镜像滤波器及其在滤波器银行应用的新节;增加一个关于使用误差反馈减小量化噪声设计最大化平坦FIR滤波器的新节;以及在整个书中增添了许多新问题。
