Time-frequency Analysis of Seismic Signals GMAT Statistics problems can make theA practical and insightful discussion of timefrequency analysis methods and technologies Timefrequency analysis of seismic signals aims to reveal the local properties of nonstationary signals. The local properties, such as time period, frequency, and spectral content, vary with time, and the time of a seismic signal is a proxy of geologic depth. Therefore, the timefrequency spectrum is composed of the frequency spectra that are generated by using the
