Abstract

PURPOSE: To obtain the unit with good response, by performing sampling at the crossing of the output signal of sensor and the pulsation averaging signal through the use of pulsation sampling signal at the superposition of pulsive voltage.
CONSTITUTION: The output of heat wave type air flow rate sensor etc. 15 is input to the maximum, minimum peak hold circuits 2, 3 via the amplifier 1, and the output is input to the analog switch 12 and AND circuit 11 via the differential amplifier 5 and comparator 7. On the other hand, the output of the amplifier 1 and the output at the neutral point A' of the maximum, minimum peak hold circuit are input to the comparator 8, and the output is input to the AND circuit 11. Further, even if the pulsation shown as figure A' is taken place at the sensor 15, the analog switch 12 supplies the pulsation cycle pulse I to the A-D converter 14 in place of the pulse H of the clock generator 13 with the output E of the comparator 7 for sampling for stable output control of sensor.
