| 摘 要： | 阐述了目前被广泛应用的对于反馈型振荡器的分析方法在描述起振条件和稳定条件时存在严重的逻辑缺陷。提出了一种普适的起振条件判据,推导出两组具体而又具有实际指导意义的起振条件判据,阐明了不存在"频率稳定条件"的理由。

| Abstract: | Because of its fatal imperfections in the logical procedure, the widely-accepted analysis in the form of phasor method applied to obtain the en-oscillating condition and the stabilizing condition for feedback oscillator prove wrong. In the paper, a general en-oscillating criterion is brought forward for the first time, and by means of this criterion, two concrete en-oscillating condition in the form ofphasor method are logically deduced, which are reasonably practicable. In the end, the stabilizing condition for oscillator is sentenced to be nothing. |
