Abstract

In order to signal the failure of periodic pulse signals, in particular the failure of a clock pulse signal, a circuit arrangement is provided in which capacitors (14, 15) are connected in each case to a dedicated charging current source (16, 17), the respective charging current circuit (14, 16; 15, 17) being connected between two logically different potentials (VH, VL) and being capable of being switched on and off by one of the inversely operating switch elements (11, 13). <IMAGE>
