Abstract

Il circuito di risposta bipolare può non solo indicare la polarità di un segnale da misurare tramite una discriminazione automatica, ma può anche supervisionare sempre uno strumento indicatore in modo che la sua lancetta si sposti in direzione positiva per raddrizzamento del segnale di misura collegando semplicemente uno strumento di misura al circuito di misura. E' pure descritto uno strumento di misura analogico che impiega il circuito di risposta bipolare ed in cui un segnale d'entrata misurato attraverso un circuito commutatore è convertito in un segnale di tensione costante. Questo segnale è convertito in un segnale di corrente costante. Questo è invertito e raddrizzato dal circuito di risposta bipolare che comprende un primo, un secondo, un terzo ed un quarto elemento direzionale.
