Abstract
A sensor signal processing device includes an AD conversion section, a filter section, a timing signal generation section, and an arithmetic section. The timing signal generation section generates a signal synchronized with a crank angle of an engine based on a signal indicating the crank angle and generates a data acquisition timing signal by compensating the signal synchronized with the crank angle with a delay time of the filter. The arithmetic section acquires a plurality of sensor signals, which is transmitted from a sensor, converted from an analog signal to a digital signal by the AD conversion section, and filtered by the filter section, in a term before and after receiving the data acquisition timing signal and generates a data synchronized with the data acquisition timing signal.
