利用Multisim求任意激励下电路的响应

Circuit Response under Arbitrary Excitation by Multisim

Multisim是一款广泛使用的EDA软件。尽管Multisim软件提供了多种激励源,但是在其元件库中并不存在一种提供任意激励波形的元件。结合教学实践,采用Multisim元件库中提供的分段线性信号源来实现任意激励源,具有简单、易用、适应性广等特点。给出了任意激励源的设置方法,包括数据点输入和数据文件输入方法,并通过例子来说明该方法在求任意激励下动态电路响应中的应用。

Multisim is a widely used EDA software. Although Multisim has supplied different sources, a source which occupied arbitrary wave does not exist. Originated from the teaching practice, an arbitrary source which is realized through piecewise linear signal source is discussed. The realizing method includes inputting data points in the set menu directly or inputting data by data file. Typical examples of circuit simulation using the created signal source are included. It is helpful for the teaching of circuit theory and analog circuits.
