摘　　要：基带传输中码间干扰的产生与消除包含了信号与系统的许多重要概念,包括信号带宽与系统带宽、不失真传输、采样与重建及系统的物理可实现性等,因此非常适合在信号与系统课程的傅立叶变换的应用部分将其取作一个综合性的实例。教学实践表明,尽早引入与基本原理密切相关的后续课程中重要论题的做法,既能使学生对所学到的基本概念、基本原理和分析方法受到综合性的训练,建立起各种概念之间的有机联系,增强将理论应用于工程问题的能力,又能为后续课程的学习打下良好的基础。The problem of the generation and elimination of inter-symbol interference in digital baseband transmission involves a lot of key essential concepts of signal and system analysis, such as signal bandwidth and system bandwidth, non-distortion transmission, sampling and reconstruction, and the physical realizable system, etc. , and therefore is well suited for taking as an comprehensive example in the course ＂Signals and Systems＂ when teaching the applications of Fourier transform. Our teaching experience of recent several years indicates that, earlier introducing some important engineering topic from the succeeding courses into fundamental courses seems of much benefit to students to understand the fundamental concepts, principles and the basic analyzing methods, and establish the inherent relationship link of various concepts, thus enhancing their ability of applying the theory to engineering practice. Meanwhile.it is also shown that this measure will also be helpful to students in succeeding course study.
