摘要
本文依据国内电子线路教材中介绍的文氏桥振荡电路,利用反馈的概念,推导出另外三种文氏桥正弦波振荡电路,对各种振荡电路在稳幅振荡时的反馈特性进行了分析,通过电路实验加以验证,理论分析与电路实验的结果一致。
Based on the Wien bridge oscillators used in domestic textbooks of electronic circuit,three other Wien bridge oscillators are designed by the concept of feed back and are tested and verified through experiments,the experimental results are in agreement with the theoretical analysis.This article has certain guidance meaning for theoretical teaching and experimental teaching of Wien bridge oscillator.
