Abstract
PURPOSE: To measure effectively characteristic parameters of a desired AE wave, by deciding the sensor which received the AE wave first and by extracting only the receiving signal.
CONSTITUTION: When sensor 1a out of plural AE sensors has received the AE wave first, FF7a is set first by the output of discriminator 4a because the signal detection dependent upon discriminator 4a is earliest. Control circuit 8 inputs the set output of FF7a to reset other FFs and resets FFs 7bW7n and sets only FF7a independently of outputs of discriminators 4bW4n. Consequently, only switch SW 5a is conductive, and the receiving signal from sensor 1a which has received the AE wave first is supplied to parameter measuring circuit 6 in an alternative way, and the characteristic parameter is measured. As a result, the characteristic parameter of the AE wave can be measured effectively.
