“通信原理”课程中基本概念的教学实践

The Cognition of Some Basic Concepts and Question of Communication Principles

“通信原理”课程的教学过程中,有相当的基本概念对学习该门课程产生一定的影响。本文就学生在“通信原理”课程的学习过程中经常涉及但容易产生疑义的几个基本概念进行了讨论:噪声平均功率SN、希尔伯特变换及其性质、数字基带传输系统中输出信号的带宽、绝对码和相对码、以及2PSK、2DPSK信号相位的变化等。通过对这些概念和问题的讨论,目的在于进一步加深学生对“通信原理”课程相关理论和概念的理解和掌握。

Some basic concepts have the＇certain influence in ＇Principles of Communications＇ curriculum teaching process. This paper discusses some basic concepts and questions in the principles of communication＇s study process, encountered frequently by students, but are easy to be misunderstanded. Noise average power SN, Hilbert transform and it＇s character, output signal bandwidth in the digital baseband transmission systems, as well as 2PSK and 2DPSK signal phase change and so on. Through to these concepts and questions discussion, the paper＇s purpose is to have students to improve the correlation content understanding and grasp the ＇principles of communication＇ well.
