Method and device for coding and of brief for the transmission series of binary data with suppression of the d.c. component.

摘要

Encoding and decoding method and device for the serial transmission of binary data with suppression of the DC component. The encoding method of the invention is derived from the encoding methods of Miller and of Miller2 in which a logic ''1'' is transmitted in the form of a middle of bit cell transition and a logic ''0'' is transmitted in the form of a start of bit cell transition, this transition being suppressed if the logic ''0'' follows a logic ''1''. In order to avoid any DC component in the encoded signal transmitted, the invention modifies the encoding of a sequence of logic ''1''s, this sequence comprising two logic ''1''s or at least four logic ''1''s, which follow a logic ''0'' loaded in the sense of Miller2. Application to the case where the transmitted signal is received in an information channel comprising an electrical or optical link, or a recording on magnetic tape. IMAGE
