概要	This paper studies on the dissimilarity of waveforms. It is shown that the dissimilarity based on the distance in the frequency domain works well in comparing the waveforms having major power at high frequency. The correctness of this dissimilarity is evaluated through the metrics used in evaluating that of the information retrieval, i.e. precision and recall. The frequency domain dissimilarity is compared with the time domain dissimilarity, which is the dissimilarity based on the distance in the time domain. The experimental result shows that the frequency domain dissimilarity works better than the time domain one in retrieving waveforms. This paper also proposes a new method of retrieving similar waveforms. The proposed method is based on the frequency domain dissimilarity. The method can be used for the subsequence matching of waveforms.
