Abstract

Un circuito (1) per la rilevazione della detonazione in un motore a ciclo otto comprende un circuito di adattamento di impedenza (A) che non risente della capacità parassita (C) dei cablaggi e non degrada il segnale. Il circuito di adattamento di impedenza (A) comprende un amplificatore invertente (OP1, Z) avente un'impedenza di reazione (Z) uguale all'impedenza di reazione (Z) uguale all'impedenza serie (Z S) del sensore (AS) impiegato. Il circuito (1) comprende inoltre un circuito di sample and hold (B) comprendente un unico operazionale (OP2).(Figura1).
