Abstract:

According to the universal relationship between periodic signals, a basic theory about phase quantum is proposed based on the equivalent phase comparison frequency. Besides the own periodic changes of frequency signals, the base of interactions and relationships between periodic signals is phase quantum, which reveals the key of the universal relationship between the periodic signals. The phase quantum is the necessary one of the periodic signals in the experiment. Measurement comparison and control based on the phase quantum may achieve direct comparison between different frequencies. The application of the phase quantum in the PLL circuit experiment of the active hydrogen maser can simplify its frequency transformation circuits, reduce the noise caused by those circuits and improve its performance.

Key words: equivalent phase comparison frequency, phase quantum, group period, phase-locked loop, periodic signals
