Abstract
This paper presents a simplified eddy-current testing system design that minimizes hardware complexity by leveraging digital signal processing (DSP). An architecture for the digital-to-analog and analog-to-digital converters is shown that ensures precise temporal correlation between transmitted and received signals. By converting these signals to in-phase and quadrature (IQ) format, additional filtering, spectral analysis and parameter tuning is possible. This design has been applied in both educational and spec-troscopic measurement contexts, demonstrating the efficiency of its implementation.
