    • A system is disclosed for synchronizing a free-swinging oscillator to a reference signal of a substantially lower frequency. A regulating circuit connects to the oscillator to control the frequency thereof. A quartz oscillator is provided for producing the reference signal. The reference signal is subsequently connected to a frequency multiplier and/or frequency divider, an amplifier and a pass band filter. An output signal from the pass band filter is fed to a harmonics mixer connected to the free-swinging oscillator and which produces a pattern of harmonics. A selective amplifier feeds an intermediate frequency obtained from the harmonics mixer to the regulator circuit. A filter also connected to the quartz oscillator produces harmonics which are also coupled to the regulating circuit. By phase or frequency comparison the regulating circuit adjusts the running frequency of the free-swinging oscillator.
    • 公开了一种用于使自由摆动振荡器与基本上较低频率的参考信号同步的系统。 调节电路连接到振荡器以控制其频率。 提供石英振荡器用于产生参考信号。 参考信号随后连接到倍频器和/或分频器,放大器和通带滤波器。 来自通带滤波器的输出信号被馈送到连接到自由摆动振荡器并且产生谐波模式的谐波混频器。 选择性放大器将从谐波混频器获得的中频馈送到调节器电路。 也连接到石英振荡器的滤波器产生也耦合到调节电路的谐波。 通过相位或频率比较,调节电路调节自由摆动振荡器的运行频率。
