本文分析了晶体管自激多谐振荡器用作双侧同步分频电路的一般理论和分频稳定性,并考虑基极电压变化规律来确定最佳分频的工作状态和运用点,同时对同步脉冲的引入问题亦作了原理性补充,还提出了振荡于第二类状态下的自激多谐振荡器可获得高稳定性的分频,以及此类双侧同步分频电路的设计方法。实验结果与理论计算基本上是一致的。 In this paper, we analyze the general theory and frequency division stability of a transistor self-excited multivibrator as a double-sided synchronous frequency divider circuit and consider the law of the base voltage to determine the optimum frequency division and operating point, The introduction of the pulse also made a principle supplement, also proposed oscillation in the second state of the self-excited multivibrator can obtain high stability of the frequency division, and the design of such bilateral synchronous frequency divider circuit. Experimental results and theoretical calculations are basically the same.
