Abstract

To compensate for frequency variation in the quartz oscillator 4, 6 due to temperature variation, a second quartz oscillator 12, 14 forming a thermal sensor is employed. The beat frequency fB (circuit 16) which is counted in the counter 26 for a period of time T1 gives a measurement corresponding to temperature. The number which is thus counted is raised to its square and by means of the comparator 30 taken away from the pulses counted by the divider 8 with a periodicity TT. The system may be used to provide temperature compensation for a time keeping quartz time base.
