The article introduces the concept deployer of high speed analog-to-digital conversion to reduce the dynamic error of the 2nd kind. It is shown that the use of high-speed deployer conversion leads to unequal capture samples of the signal. Considered the ratio of the period of the capture signal samples at a uniform sampling rate and sampling using high-speed deployer conversion, for a given interpolation error. The estimated coefficient linking the period of the uniform sampling and the period razvarivaya functions. It is shown that the recovery of signals by the Lagrange polynomial of the first degree and the use of high-speed deployer conversion, the scan period must be two times less than the period of the capture signal samples at a uniform sampling.

Keywords: the dynamic error of the 2nd kind, the discretization of signals in time, razvenchivayuschie analog-to-digital conversion, the period razvarivaya functions
