Abstract
A physical quantity detection circuit () is used for a physical quantity sensor () that outputs a sensor signal according to a physical quantity given externally. In the physical quantity detection circuit (), an analog-to-digital converter () converts an analog sensor signal (Ssnc) to a digital sensor signal (Dsnc). A digital filter () attenuates a frequency component of the digital sensor signal (Dsnc) that is higher than a predetermined cutoff frequency. A multiplier () multiplies a digital sensor signal (Dps) having passed the digital filter () by a digital detection signal (Ddet) to detect a digital physical quantity signal (Dphy).
