摘　　要：《随机信号分析》课程主要讨论随机信号的信号分析以及随机信号经过线性时不变系统后系统对随机信号的影响,即随机信号的系统分析问题;《信号与系统》课程讨论的是确知信号的系统分析问题。教学过程中采用类比分析的方法将这两门课程内容进行比较,探讨两门课程研究对象与分析方法的异同,有助于学生正确理解和掌握《随机信号分析》课程的基本概念、基本理论、及课程的体系结构,为后续专业基础课《通信原理》的学习奠定扎实的基础。Random signal analysis course mainly focuses on the signal analysis of random signal, and the influence of the random signal after through the linear time invariant system （ LTI） .The course of signal and system is discussed in the system a-nalysis of the known signals.In the process of teaching, comparing the contents of these two courses by analogy analysis, explo-ring the similarities and differences between the two courses research object and the analysis method , which is conductive to en-hance the students′abilities to correctly understand and master the basic concepts, theory, and architecture of the course.Simulta-neously, it helps students to lay a solid foundation for the study of the communication principle course.
