Abstract : The patent describes a method and apparatus for encoding and decoding clear signals of an analog nature, the amplitudes of which represent information. The method employs a key which controls the coding of the signals, a module shift and the coding of the modulo-shift, the modulo shift being transmitted by time multiplex or on a separate channel from that of the encoded signal.
