Abstract
Oscillateur étalon auto-entretenu, du type à circuit déphaseur. La boucle de réaction 1 comprend un déphaseur 2 à gain unité et à déphasage asservi à 90 degrés , en série avec un déphaseur 3 à gain unité et à déphasage réglable, en série avec un amplificateur 4 à déphasage 180 degrés et à gain unité ajustable et commandé par un dispositif 4a. Ce dispositif redresse les alternances positives et négatives de 4 tensions provenant de la sortie du déphaseur 2, de la sortie de l'amplificateur 4, et des deux sorties de deux amplificateurs sommateurs 8a et 8b à gain 2Root ;2/2, dont deux premières entrées reçoivent la tension de sortie du déphaseur 2 et dont les deuxièmes entrées reçoivent, l'une, la sortie du déphaseur 3, et l'autre, la sortie de l'amplificateur 4.
