FIELD: electrical and communications engineering. SUBSTANCE: communication channels are organized using power lines rated at 0.38, 10, 35, and 110 kV dispensing with high-frequency line traps. Method involves synchronous detection of signals using integration, its beginning and end being determined by characteristic points which are, essentially, moments of transition of total supply voltage at transmission and reception stations. Signal transmission speed of 50 to 100 bouds is attained. EFFECT: improved noise immunity and signal transmission speed. 1 dwg
