<p>A circuit is disclosed for providing a digital representation of the magnitude and polarity of current signals using only a single threshold device. A series connected pair of current converters, one of which includes a pre-set threshold, are connected with rectifier means poled to allow passage of current of a single polarity. A second rectifier means poled to pass the current of opposite polarity is connected to pass such current only to the current responsive device with threshold means, bridging the second current device. An accurate digital representation is thereby obtained, with minimal component outlay.</p> |
