Abstract
Abstract A system in which each single pulse generator is provided for producing each one single pulse representing each one information, which system including a transmitter consisting of at least two pulse signal generators for producing separate pulse signals each within a pulse duration of the single pulse on each channel, and at least two coding units provided in each channel for converting the pulse signals into corresponding binary coded signals, and a receiver consisting of at least two decoding units provided in each channel for re-converting the transmitted binary coded signals into original pulse signals.
