Abstract
PURPOSE:To avoid a malfunction caused by dissidence, by setting a storage circuit with the highest bit output of a counter that produces a comparing output and at the same time latching the digital error signal. CONSTITUTION:A flip-flop FF6 is set by the output C of an n-bit binary counter 5 that counts clock pulses CK2, and at the same time the output of an n-bit latch circuit 3 is latched to an n-bit latch circuit 7. When coincidence is obtained between the contents of the counter 5 and that of the circuit 7, an output is delivered from a coincidence circuit 4 to reset the FF6. Thus the output of the circuit 4 is obtained without fail although the output of the circuit 3, i.e., a digital error signal has a change during a comparing action.
