Claim One:
1. A method of recognising anomalies in data representative of an analogue waveform, the analogue waveform having a plurality of cycles, the data comprising an ordered sequence of data elements, each element having a respective value, the method including the steps of: (i) selecting a test group of test elements; (ii) selecting a comparison group of comparison elements; (iii) performing a comparison between the test group and the comparison group, the comparison involving the test elements of the test group on the one hand and the comparison elements of the comparison group on the other hand; (iv) determining as a result of the comparison whether there is a match or a mismatche between the test group and the comparison group; (v) repeating steps (ii), (iii), and (iv), incrementing the value of a mismatch counter each time a mismatch is found; (vi) determining an anomaly measure representative of the anomaly of one or more of the test elements, the anomaly measure being dependent on value of the mismatch counter.
