A demonstration of online real-time signal processing and cross correlation of two data streams is described. The demonstration is used to distinguish between near and far-side corrosion pit signals obtained by magnetic flux leakage detectors used in pipeline inspection. A PC-based data acquisition system is used, and an algorithm employing five simple processing stages is described. The demonstration reveals that processing speed is not a problem, however, if used as an operational tool, power requirements are likely to be a challenge.
