Error checking for an electric data transmission system for differential transmission of binary data pulses using two lines, in which the signals on both lines are differentiated each, the resulting differential signals and a reference signal are summed up to form a sum signal, the sum signal is compared with the reference signal on the one hand and the two differential signals are compared with the sum signal on the other hand, and error signals are produced from the result of these comparisons when line errors of a specific kind are present.
