Signal processing circuit, measurement device, and signal processing method |
| abstract |
A signal processing circuit (40) processes a signal based on a quantity of light detected by an infrared detector. The signal processing circuit (40) includes an IV conversion circuit (41), a filter circuit (43), and a differential converter circuit (44). The IV conversion circuit (41) converts a signal of a current value provided from the infrared detector to a signal of a voltage value. The filter circuit (43) allows passage of a signal containing a predetermined frequency component among signals converted by the IV conversion circuit (41). The differential converter circuit (44) generates a reverse-phase signal of a passed signal that has passed through the filter circuit (43) and provides a differential signal including the passed signal and the reverse-phase signal. |
