Abstract

Procédé et appareil utilisant un résonateur à cristal de quartz d'une orientation sensiblement égale à (yxwl) 21,93 degrés /38,93 degrés vibrant simultanément dans deux modes d'épaisseur pour former une source de signal de fréquence stable. En combinant un résonateur à cristal de quartz du type ci-dessus avec une compensation numérique ou analogique, on peut utiliser la déviation de fréquence en fonction de la température de l'une des fréquences de mode du cristal comme thermomètre interne et la seconde fréquence de mode du cristal comme signal de fréquence de référence. Le signal de fréquence à fonction thermométrique est utilisé par le réseau de compensation pour stabiliser la fréquence du signal de référence. Application aux horloges à quartz.
