到目前为止,还有一些文章对文氏电桥振荡器作理论的分析和实验的证明,以便用非线性特性来说明振荡信号的振幅和失真等问题。但是,还没有人从振荡系统本身的非线性特性来解决它的理论问题。本文就是补充这个不足,为设计低失真低频信号源提供理论根据。 So far, there are still some articles on the Wrigley bridge oscillator for theoretical analysis and experimental proof in order to use non-linear characteristics of oscillatory signals to illustrate the amplitude and distortion issues. However, no one has solved its theoretical problems from the non-linear nature of the oscillation system itself. This article is to supplement this issue, providing a theoretical basis for the design of low-distortion low-frequency signal source.
