MULTI-FREQUENCY QUARTZ OSCILLATING SYSTEMS USING DIGITAL COMPENSATION OF FREQUENCY INSTABILITY CAUSED BY VARIATIONS OF TEMPERATURE AND VIBRATIONS

摘要

In this paper, a problem of decreasing of frequency instability caused by variations of temperature and vibrations in quartz oscillating systems is considered. Multi-frequency quartz oscillation system and digital compensation of frequency fluctuations are suggested for solving this problem. In order to provide digital compensation of frequency instability caused by temperature and vibration influences a multi-frequency piezo-resonance oscillation system has been developed. Experimental study of suggested multi-frequency unit has been performed. Results of experimental investigations demonstrate the robustness of suggested multifrequency oscillation system to rapid variations of temperature and considerable vibrations environment.
