Abstract
Lors de l'évaluation de signaux en provenance de capteurs optiques notamment, il faut souvent reconnaître de manière fiable différents niveaux de signaux utiles. Par exemple, des marques d'épaisseurs diverses sont agencées sur le rotor de moteurs à barrillet de tête, de sorte que les marques étroites fournissent des signaux de détection ayant une valeur maximale réduite et les marques larges fournissent des signaux ayant une valeur maximale élevée. Les premiers signaux servent à commuter le moteur à barrillet de tête et les derniers à commuter les têtes magnétiques d'un magnétoscope. Etant donné les tolérances des marques et des composants du circuit d'évaluation, la distinction entre les différentes amplitudes des signaux n'est pas toujours assurée. Afin d'éliminer cet inconvénient, un circuit régulateur de signaux maintient à un niveau constant la valeur moyenne des valeurs maximales de parties sélectionnées de signaux. Ce circuit est utile dans des magnétoscopes, dans des platines à disques compacts, pour réguler en général des parties de signaux.
