Abstract

1. An apparatus for the transfer of digital signals, comprising a character transmitter and a character receiver, having a first, continuous parity counting operation performed on n bits at a time of the character stream to be transmitted and with insertion of a parity bit, dependent on the particular results of this first parity counting operation, into the character stream to be transmitted on the transmitting side, as well as a second, continuous parity counting operation performed on the same n bits of the character stream to be received and comparison of the result of this second parity counting operation with the received parity bit for the purpose of error recognition on the receiving side, characterized in that on both the transmitting side and the receiving side, the input of the parity counter (P ; Fig. 2) is in each case preceded by a scrambler (S), in such a manner that the character stream to be transmitter and the character stream to be transferred via the transfer channel (Ü) are statistically decoupled from the input data of the parity counter (P).
