Multiexponential decays may contain time-constants
differing in several orders of magnitudes. In such cases, uniform
sampling results in very long records featuring a high degree of
oversampling at the final part of the transient. Here, we analyze a
nonlinear time scale transformation to reduce the total number of
samples with minimum signal distortion, achieving an important
reduction of the computational cost of subsequent analyses. We
propose a time-varying filter whose length is optimized for minimum
mean square error.
