Abstract

PURPOSE: To simplify sorting and processing, by picking out and transcribing only a signal higher than a set level.
CONSTITUTION: An analogue signal 1, which is generated by the eddy current flaw detection test of a thin tube or the like, is converted into a digital signal at 2. A computer 4 compares the digital signal 3 with a reference level 5. The computer produces an output signal 6, only when the digital signal 3 exceeds the level 5. The wave form of the output signal 6 is recorded on a recorder 7 such as a CRT and copied on paper by a hard copy means 8.
