Abstract
SE PRESENTA UN SISTEMA COMPUESTO DE UN PROCESO Y DE UN DISPOSITIVO APROPIADO PREFERIDO PARA LA IMPLEMENTACION DEL PROCESO DE LA INVENCION, PARA LA CONVERSION TIEMPO/TENSION, QUE DETERMINA VALORES DE TENSIONES QUE CORRESPONDEN A LAS DURACIONES DE LOS IMPULSOS. LOS SISTEMAS CONOCIDOS DE LA CLASE CITADA PRESENTAN INEXACTITUDES EN LA CONVERSION TIEMPO/TENSION, POR LO CUAL SE PRESENTAN NO-LINEARIDADES. CON EL FIN DE EVITAR LAS NO-LINEARIDADES EN LA CONVERSION, DE ACUERDO CON LA INVENCION, LAS TENSIONES DE LOS IMPULSOS, CUYA DURACION SIRVE PARA LA CONVERSION TIEMPO/TENSION, SE IGUALAN A LAS CARACTERISTICAS DE UNA TENSION AUXILIAR, QUE SIRVE PARA LA FORMACION DE UNA TENSION DE SALIDA. ESTA TENSION AUXILIAR PUEDE SER UNA TENSION DESCENDENTE PROPORCIONADA POR UN GENERADOR DE TENSION DESCENDENTE U OTRA TENSION APLICADA A LOS COMPONENTES DEL DISPOSITIVO DE LA INVENCION. EL SISTEMA DE ACUERDO CON LA INVENCION SE PUEDE UTILIZAR CON PREFERENCIA COMO PARTE DE UN DISPOSITIVO AMPLIFICADOR, QUE ESTA REALIZADO EN LA TECNICA DE CAPA DELGADA Y SIRVE PARA CONTROLAR UNA PANTALLA DE CRISTAL LIQUIDO.
