Circuit arrangement for monitoring a plurality of busbars

摘要

In the case of the proposed circuit arrangement, the busbars of a digital system which is in operation are connected successively, for a characteristic time, to the clock input of a flipflop, with the aid of a multiplexer and a control unit. If the state of the flipflop does not change during the time in which it is connected to the busbar, this is a sign that no information interchange has taken place on the relevant busbar and that a defect must therefore be present.
