Abstract :
Practical results are presented on a novel method for compensating the frequency drift of crystal oscillators. The digital summing of a 300 kHz quartz and a 200 kHz LiTaO3 crystal resonator results in a sum frequency whose temperature drift is 10 times smaller than the drift of quartz or LiTaO3.
