<P>PROBLEM TO BE SOLVED: To provide a physical quantity detector capable of selecting which of securing high responsiveness and reducing noise components has a higher priority according to detection results while holding the quality of detection results of a prescribed physical quantity without applying any loads to a CPU for processing the detection results. <P>SOLUTION: The physical quantity detector 1 includes a sensor 10 and a low-pass filter 20. The sensor 10 detects a prescribed physical quantity and outputs detection signals having a voltage value corresponding to the value of the detected physical quantity. The low-pass filter 20 is composed as a VCVS-type low-pass filter capable of setting a cut-off frequency to a first frequency or a second frequency lower than the first frequency by a control signal 50a generated based on a detection signal 10a of the sensor 10. <P>COPYRIGHT: (C)2010,JPO&INPIT |
