Comparison between Time-domain and Frequency-domain Measurement Techniques for Mantle Shear-wave Att data to verify the results from the synthetic tests. For the . waveforms, the primary biasing factors are interference with seismic phases due to mantle discontinuities and due to crustal reverberation under the . bounce point. These factors can affect the .* measurements by up to 0.5 s in the freq

A Model to Study the Bias on , Estimates Obtained by Applying the Rise Time Method to Earthquake Datto distinguish two different corner frequency ranges in which the trend is different. When corner frequency is below 10 Hz the discrepancies with the rise time method increase with a decrease of the corner frequency. When corner frequency is above 10 Hz no meaningful differences are observed..The ap
