Beschreibung
Zusammenfassung:	A pressure detection signal processing device, engine control system, and non-transitory computer readable medium storing a program are provided. A current-voltage conversion part that converts a current signal corresponding to charge generated by a piezoelectric element in accordance with received pressure into a voltage signal, and digital signal processing parts that perform correction for removing a drift caused by a leakage current of the piezoelectric element on the voltage signal through digital signal processing are provided. The digital signal processing parts include a differentiation processing part that performs differentiation processing on the voltage signal, an integration processing part that performs integration processing on the signal having been subjected to the differentiation processing, and an integration processing part that further performs integration processing on the signal having been subjected to the integration processing.
