Circuit processing input signals into control signals - has monitoring device which delays final evaluation of output signals until undefined state dies down

摘要

The input signals arrived at undefined times at an interface between digital, independently operating functional units. Decision elements are connected to one of the input lines, responding to a level change in an input signal. A monitoring device (WS) also consisting of decision elements is allocated to the decision elements (SF). It delivers a warning signal (W) when one of the decision elements is undefinable controlled by an input signal which delays the final evaluation of the output signal of the undefinable controlled decision element until the undefined operational state dies down.
