基于EWB软件的模拟电路实验仿真分析

传统的电子线路设计由于受工作环境、仪器设备和元器件品种、数量的限制,有些实验往往无法完成.既影响了设计工作的顺利进行,又束缚了设计者的创造性思维.基于EWB的电子实验设计可以弥补上述不足,将不同类型的电路组合成混合电路进行仿真.可以进行各种类型、不同层次的电子线路设计、分析,以及修改与优化电路.着重介绍了EWB软件的主要功能和特点.结合共射极单级放大电路的分析过程,说明了EWB软件的使用方法及对实际电子线路进行仿真的基本步骤.

Emulation Analysis of Simulated Circuit Experiment Based on EWB Software

Some experiments of traditional electronic circuit design cannot be fulfilled because of the working conditions, the instruments, equipments, species and numbers of the advance. This not only affects the advance of the design but also limits the creative thinking of the designer. The design of the electronic experiment based on EWB can counteract the weakness mentioned above and combine various circuits into a combining circuit to emulate. It can also design,analyze,revise and optimize all kinds of electronic circuits at different levels. This essay introduces the main function and characteristic of EWB software. Combining the analyzing process of one -way amplifying circuit,it illustrates the usage of EWB software and the basic steps of emulating the actual electron magnitudes of way.
