Abstract
PURPOSE: To enable to detect the continuity of "0" for a given period of input signal with a simple constitution, by reading out the "0" level of input signal with the first FF and reading out the output with the second FF in the advanced clock.
CONSTITUTION: In the unit handling digital signal, when the continuity of zero code is, for example, detected, FF1 is reset when the signal input is "1" and the output terminal Q is "0" level. Further, when the clock b having lower frequency than the fundametnal repetitive period of the signal a is fed to the terminal T of FF1, FF1 delivers "1" to the output terminal Q every leading time of the clock b. In this case, "1" is caused when the input signal a is "0" to the reset terminal, and it continues unit "1" is incoming to the signal a. The Q output is read out with FF2 by the clock d advanced with the rate of the delay circuit 3 of FF1. Thus, the continuity of "0" for a given period of the signal a can be detected with a simple constitution.
