Abstract
A double detector dc comparator with magnetic modulator and magnetic amplifier is disclosed. The synthetic output characteristic of the double detector has one operating point corresponding to zero ampere turns, not other zero output points, the so called false-balance points. The comparator possesses not only high precision, low drift, high linearity and good antimagnetic property from magnetic modulator comparators, but also perfect stability and reliability from magnetic amplifiers. The performance and test results are described
