Abstract

Circuit de démagnétisation appartenant à un récepteur d'images de télévision en couleur et comportant une bobine de démagnétisation branchée en série avec un thermistor à coefficient de température positif, ce thermistor étant couplé thermiquement à un thermistor à coefficient de température négatif. Ce dernier constitue également une résistance de protection pour un circuit redresseur dans le récepteur. Application aux récepteurs d'images de télévision en couleur.
