Result vibroseismic sounding the grounds is "photo" of an earth's crust as seismo-grams. She shows a transit time of seismic waves that set reflects structure of researched area of a terrestrial surface. Quality seismogram depends on parity a useful signal - seismic noise and resolution "photo". At traditional processing the seismic data procedure of convolution for the signals submitted in time space is used. Alternative way of processing vibroseismic the data is procedure of convolution of the same signals submitted in frequency space. In the report results of research of features of use of procedure of convolution for signals in fre-quency and time space are submitted. By the example of two-layer model vibroseismic ex-periment with normal stationary noise identity of use of procedure of convolution is shown at various representations of signals. Identity of use of procedure of convolution is considered by two criteria: Resolution seismograms and the attitude a useful signal - seismic noise. Features of formation vibroseismic seismograms, characteristic for frequency and time space are considered.
