Abstract: An error-correcting device for the transmission of data on a telegraph line with modulation by coded pulses (MIC) whose sampling sequence is more rapid than the telegraphic speed (number of bits per second), which leads to transmitting in the MIC pattern information bits, doubling bits, called ''''padded bits,'''' as well as supplementary bits, called ''''packing or padded indications,'''' which make it possible to recognize whether a given bit is an information bit or a padded bit. The succession of the valances of the packing indications follows a well defined law. The invention furnishes the means to carry out a correction if this law is not complied with.
