Processing circuit signals delivered by two sensors measuring differential mode a physical magnitude.

摘要

The invention relates to a circuit signal processing (S1, S2) SUPPLIED BY TWO SENSORS (6.12; 8.14) MEASURING differential mode a physical quantity, and supply a signal representative of this magnitude. This processing circuit consists essentially of a first accounting (18) to post WITHIN A PERIOD OF MEASURING A WHOLE NUMBER N1 PERIODS T1 SIGNAL S1, a second accounting (209 to account INSIDE SUCH A measurement period WHOLE NUMBER OF PERIODS N2 T2 S2 SIGNAL, AND LOGIC CIRCUIT (22) to provide a signal SM REPRESENTATIVE OF THE DIFFERENCE BETWEEN LIFE AND DURATION N1.T1 N2.T2, being representative SIGNAL MAGNITUDE VALUE OF PHYSICS. implementation, in particular, in measuring acceleration, a force, a pressure and temperature.
