FIELD: electricity. ^ SUBSTANCE: conversion method of binary signal to five-level signal consists in the fact that zero in input data is transmitted bit by bit to the line as zero, and when combination 10 or 11 is supplied in input data, the first unit bit is retained in delay trigger and zeroised; delayed bit is supplied to input of toggle trigger, and being addressed with value of output signal of toggle trigger and with the value of the second bit of combination, the delayed bit is supplied to one of four inputs of five-level shaper of output signal which supplies pulses to the line when the unit bit appears at inputs. ^ EFFECT: increasing carrying capacity of communication channel. ^ 3 dwg |
