SUMMARY Working in the complex demodulate domain allows elegant and efficient analysis of broadband three‐component seismic data recorded at a single station. The analysis procedures are based upon the auto‐ and cross‐covariances of the various pairs of components, and allow effective decomposition of many recorded time series into ‘phases’ according to frequency, wave type, direction of propagation, and apparent surface velocity or ellipticity.
