Abstract
Frequency spectrum analysis is introduced to eddy current nondestructive testing. From the equivalent circuit of the eddy current testing system, the eddy current testing system is derived to be a second-order system and the characteristic of the output response signal for the square wave of the eddy current testing system is given. Then the frequency spectrum of the eddy current testing system output signal is analyzed. Finally, experimental results are given to show that the frequency analysis method for testing multiparameters is feasible and practical in use.
