1. A system for wavelet analysis of one or more signals to determine one or more characteristics of one or more anomalies in a wire, the system comprising: a library of one or more reference wavelet analysis results that each correspond to one or more known anomalies having one or more known characteristics; and an analysis module operable to: receive a first signal from a detector that has scanned a magnetic field from a wire comprising an anomaly, the first signal corresponding to a second signal used to generate the magnetic field; calculate a wavelet analysis result from a wavelet analysis of the first signal, the wavelet analysis result corresponding to the second signal; access the library; compare the wavelet analysis result with one or more reference wavelet analysis results; if the wavelet analysis result corresponds to one or more particular reference wavelet analysis results, indicate that the anomaly in the wire has one or more particular known characteristics of one or more particular known anomalies corresponding to the one or more particular reference wavelet analysis results; and if the wavelet analysis result does not correspond to one or more reference wavelet analysis results, indicate that the anomaly in the wire lacks one or more known characteristics of one or more known anomalies corresponding to one or more reference wavelet analysis results in the library.
