SYSTEM FOR DIGITAL INFORMATION TRANSMISSION Russian patent published in 2011 - IPC G08C19/28 

FIELD: information technology.

SUBSTANCE: system for digital information transmission has at the transmitting side an information source, a first analogue-to-digital converter, a digital-to-analogue converter and series-connected subtractor, amplifier and second analogue-to-digital converter connected to a communication channel. At the receiving side, the system has series-connected code-to-pulse amplitude converter which is connected to the communication channel, a sampling value increment converter and determiner, the inputs of which are connected to outputs of a threshold level generator, an integrator, a low-pass filter and an information recipient. The sampling value increment converter has a sampling value converter, a switch and a comparator unit.

EFFECT: high accuracy of transmitted information at fixed values of the dynamic range of primary signal values.
