DATA TRANSMISSION METHOD Russian patent published in 2003 - IPC

FIELD: data transmission over wire communication lines. SUBSTANCE: method is characterized in that signal encoded for transmission is shaped from source binary code in the form of triple-layer code that has two unlike-polarity and one zero voltage levels; zero voltage level is inserted in bits transmitting one logic meaning. Novelty is that zero voltage level is inserted in bits transmitting logic zeroes so that length of respective bit intervals increases by one third compared with those transmitting logic ones; initial phase of signals for bits of both logic levels does not change and equals zero. EFFECT: enhanced transmission range. 18 dwg
