Abstract
A circuit arrangement for an analytical function generator with a capacitive differential transducer for editing the signals measured by the differential transducer into a transmittable signal at the output of the circuit arrangement which comprises two coupled RC-oscillators, wherein a first of the two oscillators is arranged in the feedback of the second of the two oscillators and the capacitance of the two oscillators is formed by one of the two partial capacitances of the differential transducer, two bistable trigger circuits connecting the two oscillators with one another, wherein one of the two trigger circuits causes a level inversion, and a gate for the linkage of the partial signals appearing at the output of the two trigger circuits so that a logic twin pulse signal corresponding to the measured magnitude or variable is generated at the output of the gate.
