<p>Circuit for monitoring a pulse train (P) comprising an input stage (K1) to which are fed the pulses to be monitored, and circuit means in order to determine the presence of a pulse of said train. If in a predeterminable time interval no pulse is observed in the circuit input stage, an output stage of said circuit is activated which provides an output pulse train (BR) and an error signal (ER).</p> |
