摘要
介绍了一个新增实验———用频谱分析仪测量信号的失真度。该实验借助自编的多媒体课件将学生轻松带入频域环境中,不但学会在频域中观察和测量相关的电参数,同时还激发出许多奇想。本文还介绍了该实验的原理、实验方法和最终达到的效果。
This paper introduced a new experiment-measuring signal distortion by using a spectrum analyzer. The experiment can easily bring students to frequency field with multimedia teaching courseware. Students can not only know how to observe and to measure in frequency field, but also be aroused a lot of imaginations. This paper also presented the experimental principle, method and achieved effect.
