Abstract A device is provided for correcting errors in the course of the transmission and arithmetical processing of information in digital computers employing a system of residual classes. The device comprises a first arithmetical unit of the computer in which signals corresponding to residues Alpha 1, Alpha 2, ..., Alpha n by the radices P1, P2, ... Pn representing the number to be analyzed are fed to selected inputs of the computer, and a second arithmetical unit to whose inputs signals are fed corresponding to the residues Alpha n 1, Alpha n 2 by the excess radices Pn 1 and Pn 2. The inputs of a constant storage unit are connected to the outputs of the first arithmetical unit whereas the outputs of the storage unit are connected to other common inputs of both arithmetical units for successive conversion of the number to be analyzed to another number of the nth order, the latter being in the same numerical range with the number to be analyzed. An analyzing unit of the two last numbers for zero is connected at its inputs to the second arithmetical unit and at its outputs to the common inputs of both said arithmetical units for detecting an error and a correction number. Finally, a control unit is connected to the inputs of the constant storage unit, the second arithmetical unit and the analyzing unit.
