Abstract
A filter apparatus (2) is disclosed for filtering out any reoccurring noise (5) present in a defect signal (1) received from a flaw detection device (4) such as an eddy current test probe. Filter circuit means (10) receives the defect signal generated by the flaw detector device and produces an output signal (5) duplicative of any reoccurring noise present therein. A differential amplifier (50) subtracts the output signal (5) of the filter circuit means from the defect signal (1) generated by the flaw detection device and amplifies the difference. A filtered defect signal (9) void of any reoccurring noise is thereby produced.
