其他摘要：Random signal by the linear system is an important content in the teaching of random signal analysis. Random signal by the linear system involves linear system theory and time frequency domain analysis theory of signal, which lead students to understand and grasp the contents of this part uneasily. In this paper, the linear time invariant system and the narrow band system are introduced firstly, and then the signal of the linear system is analyzed respectively from the time domain and the frequency domain. The white noise is also analyzed by linear system. Finally, designing examples and experiments make students know how to use the content of this part. This article has some guidance to the teaching of random signal by the linear system and can help students to better understand and apply.
