| Abstract: | The fundamental principle and present status of rubidium atom frequency standard was introduced in the paper . The scheme was presented that adopting digital phase locking frequency modulation circuit to take the place of origin variode phase modulation circuit in order to stimulate the frequency modulation of quantum system signals , and it was pointed out that adopting digital servo circuit to replace origin analog compensation circuit . The temperature coefficient and instability caused by electric circuit imperfections would be eliminated. |
