The results of experimental researches of influencing a sampling interval of registered acceleration and speed oscillation signals on amplitudes the signals of speed and displacement, after fulfillment the conversions operations are reviewed. Are shown the main regularity a change of signals speed and displacement output amplitudes from time of conversion at given sampling intervals. Is determined, that the sampling interval does not influence to change a maximum amplitudes of converted signals provided that the conversion implements from time constants, that value is peer to which one to half part of period a speed and acceleration oscillations input signals.
