Abstract

PURPOSE: To ensure the steady binary coding for the micro-signal caused by the flaw by compounding the signal region which receives no noise effect for the two binary coding signals obtained through the binary coding with each threshold level to have the final binary coding and then making clear the external shape of the tested object.
CONSTITUTION: The input signal containing the micro-amplitude signal is applied to attenuator 3 and then compared through comparator 5 after the level adjustment given to the output or the input signal. Furthermore, a comparison is given through comparator 6 after the level adjustment for the output or input signal of attenuator 4 whose threshold level becomes opposite to comparator 5. Then either left or right side of the output signal of comparator circuit 6 is extracted through AND circuit 9, and then either left or right side of the output of comparator 5 is extracted through AND circuit 8 to obtain the binary coding signal after giving OR10 the output of circuits 8 and 9. As a result, the noise effect is eliminated for the rise and fall of the input signal with the external shape of the tested object made clear, thus ensuring the steady binary coding for the signal of a micro-amplitude caused by the flaw.
