Diode-quad bridge for reactive transducers and FM discriminators
Dean R. Harrison, John Dimeff · NASA STI Repository (National Aeronautics and Space Administration) · 1972
Diode-quad bridge circuit was developed for use with pressure-sensitive capacitive transducers, liquid-level measuring devices, proximity deflection sensors, and inductive displacement sensors. It may also be used as FM discriminator and as universal impedance bridge.
