The efficiency of algorithms for adaptive time sampling (ATS) compared to the uniform time sampling (UTS) is defined in this property the analog signal as its compressibility. In order theoretical estimates of the compressibility of the measuring signals discusses the dependence of the current beat of the measure under ideal in terms of quality playback ATS from the dynamic properties of the signal. Signal recovery after ATS is made by extrapolation by a polynomial of n-th degree. The quality of approximation is determined according to the criterion of uniform approximation. For the extended area of the margin of error of reproduction is proposed as the dynamic properties of the signal to use its structural properties. In the case of a polynomial of the 0-th degree obtained functional dependence of the current measure measurement of the structural properties of the signal, allowing it to determine the average quantum duration of the measurement for ATS.
