Abstract

Improvements made to the object of main patent no. 2. 262.165, for "Improvements in data transmission systems", which include a procedure for the determination and correction of errors that appear in the transmission of groups of data that are encoded with test data with an encoder, in which by storing and adding the data to be transmitted, test data is derived and transmitted together with the information data and a decoder in which, by storing and adding the transmitted data, a data group error is determined and corrected, Said improvements characterized in that in the decoder the transmitted data of a data group are successively parallel to a displacement accumulator and to a circuit, characteristic digit computer during the delivery time of the data group to the displacement accumulator and because the circuit Characteristic digit computer is linked with an error testing circuit, which corrects the data set q It exits the shift accumulator during the exit time of the shift accumulator data group.
