改编者序
    自教育部于2001年出台《关于加强高等学校本科教学工作提高教学质量的若干意见》以来，双语教学工作在许多高校开展起来，尽管对于双语教学的意义、效果的讨论一直没有中断过，但发展现状表明双语教学仍在较为迅速地发展。
    不同院校开展双语教学的层次不同，最基本的要求是采用原版教材，主要是学习国外先进的教学思想，科学技术和语言文化；由于文化传统、教学体系的差异，原版教材与我国教学体系和教学习惯的矛盾是存在的。
    “数字信号处理”是开展双语教学较早、较为普及的课程，很多学校都选择了Sanjit K. Mitra 编写的本书第二版的影印版作为课本。Mitra 博士是国际著名的信号处理专家、 IEEE 电路与系统学会的主席和多家国际著名学术刊物的编委，他的教材不仅详细介绍了数字信号处理的经典内容，也介绍了许多数字信号处理的最新发展及应用实例，是理论与实践结合的典范。书中有大量的例题、高质量的练习题和上机仿真作业，并用 MATLAB 来演示结果。该教材在美国加州大学、哥伦比亚大学、明尼苏达大学等著名大学使用，销量大。
    原版教材的内容叙述非常详尽，实践性强，使得原版书通常很厚，容量是国内自编教材的几倍。国内的高校数字信号处理课程基本是一个学期完成的，因此在实际的教学过程中，教材的1/3内容基本不涉及。由于国内双语教学的开展还没有系统化，学生的英文水平也有较大差异，造成了学生的学习负担加重。因此，对原版教材进行改编，以适应国内课程内容及教学改革的要求，都是一件有意义的工作。
    该书第三版出版后，电子工业出版社委托我进行了改编，取得了较好的效果。第四版与第三版相比，作者根据教师与学生的反馈意见，进行了较大的改动与修订；为此，电子工业出版社继续委托我对此书进行了改编。
在改编教材的过程中，主要考虑是在保证教学内容的前提下，压缩教材的篇幅，减轻学生的学习负担；同时兼顾到不同院校的具体教学大纲，尽可能使选择的内容覆盖中文数字信号处理的内容。与原版教材相比，改动如下：删除了1.4.1节、4.8.5节和4.8.6节、5.11节至5.14节、7.4.5节、7.5节、7.7节至7.9节、8.7节、8.9.2节、8.10节至8.12节、9.7节、10.6节、11.8节和11.9节，第12章全部、第13章全部、第14章全部、附录C。教材的编排仍沿用原版教材的体系，仅对删除相关内容后的全书进行了标题序号调整、引用调整等。
原书附带光盘一张，为降低图书成本，改编后的本书，其光盘内容放在华信教育资料网上，请读者自www.hxedu.com.cn下载。
