Abstract
A signal processing system according to the present disclosure includes a difference calculation unit and a determination unit. The difference calculation unit uses a sensor signal at a reference timing and a plurality of the sensor signals at a plurality of comparative timings shifted from the reference timing. The difference calculation unit generates a plurality of differential signals as respective differences between the sensor signal at the reference timing and the plurality of the sensor signals at the plurality of comparative timings and obtains respective magnitudes of the plurality of differential signals as a plurality of differential values. The determination unit obtains an evaluation value based on the plurality of differential values and determines a property of the object by using the evaluation value.
