摘要
非线性电子网络如果寄生周期振荡 ,用 Fourier级数展开可以将该网络划分成基波与非基波两部份。非基波成份的存在依赖于基波 ,而基波成份保持自激 ,依靠本身的反馈 ,用基波分部网络去替换非线性网络 ,尽管两者建立的振荡波形不同 ,但关于稳定性的判断结果是一致的 ,而基波成份的稳定性可以采用线性正弦量的分析方法。
If the periodic parasite oscillation can be established in the nonlinear electronic network, it may be divided into fundamental and non-fundamental wave components by means of Fourier series. Existence of non-fundamental wave component depends on excitation of fundamental wave component. The feedback in fundamental wave component network ensures its self-excitation. Therefore the fundamental wave component network can substitute for original nonlinear network. Even though established oscillation wave are distinct in both cases, the judgement on stability is identical. Eventually, the stability of the fundamental wave component networks can be judged by means of linear sinusoidal analytical method.
