说明：  数字信号处理的理论和matlab实现的外文书籍，对专业的学习和实践很有帮助。
(The book is an outgrowth of our teaching of a MATLAB-based undergraduate DSP course over several years. Most of the MATLAB functions discussed in this book were developed in this course. These functions are collected in the book toolbox called DSPUM and are available online on the book’s companion website.)
