A Discrete Fourier Transform-Based Signal Processing Method for an Eddy Current Detection Sensor

A Discrete Fourier Transform-Based Signal Processing Method for an Eddy Current Detection Sensor

This paper presents a discrete Fourier transform (DFT)-based signal processing framework for eddy current non-destructive testing (NDT), aiming to enhance signal quality for precise defect characterization in critical nuclear components. By enforcing strict periodicity matching between sampling poin...
