FAILSAFE DECISION CIRCUIT

摘要

. IMPROVEMENTS IN OR RELATING TO DECISION CIRCUITS. A decision circuit (20) is responsive to digital input signals (22) and to timing signals (21) for reshaping and retiming the input signals into reshaped and retimed output signals. The decision circuit also is responsive to the digital input signals and absence of the timing signals for reshaping but not retiming the digital input signals into reshaped output signals which are transmitted. Thus the circuit produces and transmits reshaped output signals even upon failure to apply the timing signals as required by previous decision circuits.
