摘要
针对文氏电桥硬件电路实验可观测性不强、参数调整不灵活等问题,设计一种基于Multisim的文氏电桥振荡电路实验。利用Multisim对文氏电桥进行电路设计与仿真,动态再现文氏电桥振荡电路的工作过程,实现对电路起振、平衡过程、选频特性等电路机制的实验观测与验证,弥补硬件电路的不足,提高实验教学效果。
Aiming at the problems of poor observability and inflexible parameter adjustment in the hardware circuit experiment of Wien bridge,a Multisim-based Wien bridge oscillator experiment is designed,realizing the circuit design and simulation.With the help of Multisim,the working process of Wien bridge oscillator is dynamically reproduced,with experimental observation and verification of circuit mechanisms implemented,including circuit oscillation,balance process,frequency-selecting property,etc.The simulation experiment makes up for the shortcomings of hardware circuit and improves the experiment teaching.
