Abstract

PURPOSE:To maintain the operation of a frequency control loop even when a resonance signal level varies, by providing a signal amplifier with an automatic gain control circuit so that a signal level of the double wave of a modulated wave will invariably be constnat. CONSTITUTION:Of the resonance signal of atomic resonator 1, the double wave is amplified by amplifier 18 and selective amplifier 21. In this case, amplifier 20 is so controlled by automatic gain control circuit 23 that the output level of selecting amplifier 21 will be constant. As a result, the fundamental wave passing through selective amplidier 19 is also amplified to a constant level, so that even if the level of atomic resonator 1 falls, voltage-control crystal oscillator 8 can be controlled through phase detector 20.
