Abstract

A method and a circuit are described for indicating different input signal states, in which a signalling device is activated or de-activated continuously or intermittently. This happens in such a way that levels (U2, U3) are provided for intermittent operation which differ from the levels for continuous activation (U4) or de-activation (U1). <IMAGE>
