The present invention relates to a method and a system for compressing data D(nT) representing a time dependent signal A(t) comprising time dependent partial signals Aj(t). A plurality of spectra Sj(f) of the partial signals Aj(t) are received, and a plurality of amplitudes aj,j (121-126) of a plurality of frequencies fj (111-116) present in the partial signals Aj(t) is computed. Thereafter, a plurality of normalised amplitudes bj,j (141-146) is computed from the plurality of amplitudes aj,j (121-126). Subsequently, for each frequency fj (111-116), the plurality of normalised amplitudes bj,j (141-146) are modelled based on a distribution with respect to a threshold value, and model parameters MPj are obtained. Subsequently, a compressed data set CDS comprising MPj is generated for compressing the data D(nT). |
