ABSTRACT:
For each line of scan of an original text, a compressed facsimile signal for transmission, particularly through analog modems, comprises a phase synchronizing signal (S), a control flag signal (F), and a graphic signal section (P) which comprises a succession of signal blocks (P.sub.2 -P.sub.5, P.sub.8) representative of graphic blocks comprising black areas on the original text with signal block representative of graphic blocks, each consisting of a white area, deleted from the succession. A white signal piece (W.sub.1) of a preselected duration is interposed between two adjacent signal blocks in the succession only when the two adjacent signal blocks do not represent the graphic blocks which are continuous also on the original text. The preselected duration is preferably of the duration of each control flag (f.sub.1 -f.sub.10) in the control flag signal.
