以非线性理论阐述反馈振荡器的频率与幅度的稳定性

Describing frequency and amplitude stability of a feed oscillator by nonlinear theory

本文首先对线性的频率稳定理论用于近似正弦反馈振荡器的线性频率稳定理论,进行了评论性的回顾。在这方面,解释所谓的线性振荡器是清楚的。其后,是应用描述函数法和判决方程法所得到新的表达式,去阐述反馈振荡器考虑成一个非线性网络时的振荡频率和振荡幅度的稳定性。

At first, stability theory of linear frequency which is applied to that ofan approximate sinusoidal feed oscillator is reviewed and looked back by authod. Inthis hand, explanation about so called 'linear oscillator' is clear. Then, the newexpressions obtained by describing function and decision equations are used to des-cribe stabilities of oscillating frequency and amplitude when the feed oscillator isconsidered as a nonlinear network.
