美国麻省理工学院教授奥本海姆(A. V. Oppenheim)是信号处理领域中的佼佼者,他的几本信号和信号处理著作已成为享誉世界的经典力作。本书的**代著作《数字信号处理》(1975年版)被认为是这一领域的经典教材。他系统地总结了数字信号处理基本理论、基本概念和规律,全书概念清晰,逻辑性强,推理严密,是一本极好的数字信号处理教材。我国一些院校在70年代末及80年代初相继开设数字信号处理课程,在此期间奥本海姆本人来我国到清华及其他兄弟院校讲学;他的讲课录像带曾在国内广为流传。此后我国陆续出版的数字信号处理教材大多参考奥本海姆著作的体系写成。
随着时代的发展,作为新兴学科,与数字信号处理有关的新理论、新概念、新算法、新应用不断涌现。时隔二十年后,为适应形势的发展,对教学内容有新的需求。1989年,奥本海姆出版了《离散时间信号处理》一书(**版),该书在原书的基础上做了大幅度调整,着重于基础内容的加强和更新,对一些新发展的基础性专题论述更为详细,基本概念阐述更加清晰,内容安排更为合理,同时大大增加例题和习题。
1999年,奥本海姆又把《离散时间信号处理》作了必要的修改,以第二版形式出
