Abstract

Commutateur sélecteur électronique destiné particulièrement à un usage télémétrique pour radiosondes, au moyen duquel un groupe d'impédances à mesurer est relié au circuit de mesure. Le commutateur électronique est constitué par un ensemble d'inverseurs CMOS ou tout dispositif similaire 6, 71 ... 7N , les sorties b1 ... BN de divers amplificateurs 71 ... 7N de cet ensemble étant reliées chacune à l'impédance mesurée CM1 ... CM2 , les entrées a1 ... aN étant reliées à un circuit 8 à action en pas-à-pas, et le signal CM1 ... CM2 à mesurer étant dirigé vers la sortie du circuit de mesure à partir de l'alimentation en tension VDD; VDS de l'ensemble CMOS 6 ou analogue. Principales applications : télémétrie pour radiosondes.
