Abstract

The invention concerns a technique of the signal transmission and can be used in the electric signal transmission in a sound channel. The aim of the invention is radical upgrading of the quality and authenticity of the electric signal transmission through a sound channel. The method ensures the non-distorted and authentic electric signal transmission through electronic devices of a sound channel by circuits having open-ended input, and the signal transmission with the frequency more than Ohz is realised by forming a signal of the dc negative feedback in electronic devices independent on the asymmetry of electric signals.
