Abstract
Repetitive defect signals are produced, for example, by bar or rod inspection equipment whenever any one of plural roll sets in a rolling mill develops a roll crack. Defect signal repetitive rate differs for each roll's relative speed. Selective correlator electronics process the defect signals with plural repetitive rates and produce an output signal indicative of which roll set in the mill has a cracked roll.
