Abstract

PURPOSE:To increase the accuracy for detection of flaws, by giving a binary coding only to the signal component having a desired polarity among the signal component that are superposed on the background level of an input signal. CONSTITUTION:A differentiating circuit consists of a delaying circuit 30 and an adder 31 and differentiates an input signal (a); and the positive and negative pulse components of the input signal are sent to positive and negative pulse detecting circuits 32 and 33 respectively. In case when the input signal contains a signal component having a lower level than the background level, the differential signal (b) is first detected by the negative pulse detecting circuit 33 for its negative pulse. Then the positive pulse is detected by the detecting circuit 32 after the operation of a monostable multivibrator 34 is started. Accordingly a positive pulse detection signal (c) becomes ''1'' during the period of ''1'' of the output of the vibrator 34. As a result, the output (f) of an AND circuit 35 becomes ''1''. Thus only the signal component having a lower level than the background level can be binary coded to increase the accuracy for detection of flaws.
