In the article elements of the distributed systems using the principle of scanning for analog digital conversion and a data interchange are considered. The main attention is paid to the unrolling analog digital conversion of signals with further restoration of analog data with the given accuracy. Distinctive feature of the unrolling conversion is that value of counting of a signal contains information on time from the beginning of conversion. The formulas connecting value of counting of an analog signal over time of counting taking are given in article. This feature is used further for upgrade of formulas of Lagrange. In operation restoration of analog signals with use of formulas of Lagrange after their sampling on time using the unrolling analog digital conversion is considered. It is shown that use of the upgraded Lagrange's formulas doesn't lead to increase in computing expenses, but requires for restoration only value of counting.
