Abstract
A processing circuit is provided for signals (S.sub.1, S.sub.2) supplied by two transducers measuring a physical quantity parameter in a differential mode and delivering a signal representative of this parameter. This processing circuit essentially comprises a first counter for counting within a measurement period an integer N.sub.1 of periods T.sub.1 of the signal S.sub.1, a second counter for counting within this period of measurement an integer N.sub.2 of periods T.sub.2 of the signal S.sub.2, and a logic circuit to deliver a signal S.sub.m representative of the difference between the interval N.sub.1 .multidot.T.sub.1 and the interval N.sub.2 .multidot.T.sub.2, this signal being representative of the value of the physical parameter. The circuit is useful for measuring acceleration, force, pressure or temperature.
