Abstract

Inngangskrets for å kondisjonere et styresignal med forskjellige bølgeformer og spenningsnivåer, innbefattende et par med inngangstermlnaler med en metall- oksydvarlstor (10) forbundet derover. En terminal (8) er forbundet med basisen til en transistor (0) via en motstand (R2), Idet emltteren til transistoren (0) driver en optokopler (16, 20) for å isolere styre- slgnalet fra en mikroprosessor (24) som mottar styreslgnaler over en inverter (22) som har en Schmltt- triggerinngang.
