More Information
Summary:At least two signals in a message form a security unit, and signal elements of a security signal, derived from a security unit signals, are uniformly distributed over the security unit signals and form the test marking of each signal; when several signals are simultaneously transmitted over separate channels, signals of a security unit are cyclically distributed over the channels; security unit signals are transmitted staggered in time or simultaneously. Mixing of signals and inadvertent changing of signal channels is prevented. The system may be used for transmission of facsimile signals.
