In the article the analysis of some factors resulting the validity of discrete data transmission via wire lines is given. The ways to improve the quality of transmission of digital MFT signals are offered. The structure of the transmitting device with the improved characteristics is examined. The optimal ratio of some parameters in performance options of device assemblies is proved.
