Abstract
The device determines the error rate by the periodic evaluation of the parity of a pre-determined number of bits, the synchronism of said evaluation at transmission and reception being ensured by the recognition of a predetermined sequence in the binary information signal, the parity information being transmitted by an auxiliary modulation independent of that of the information flow.
