Abstract

Mejoras en oscilaciones de barrido caracterizado por un circuito de abastecimiento de campo que comprenda una bobina para producir un campo magnético, medios para suministrar a dicha bobina un voltaje de excitación que tienen una tasa de modificación determinada, medios que incluyen una bobina de toma de campo para controlar al voltaje de excitación, y medios para aplicar el voltaje desde dicha bobina de toma a dichos medios suministradores de voltaje de excitación en el mismo sentido con respecto a tierra sin perjuicio de la dirección del voltaje en dicha bobina de toma.
