In many applications, a circuit arrangement is powered by several regulated DC voltage sources and it is desirable to have a device for indicating an alarm condition whenever one of the voltage sources fails. The figure illustrates a circuit which provides an alarm signal in case of voltage source failure, based on the use of logic gates.
