Abstract
Carrier currents have hitherto been employed, in the field of electrical communication, only for working simultaneously a number of telegraph and telephone channels over the same circuit. My recent investigations have shown the possibility of their application in an entirely new direction, namely, in the problem of repeatering telegraph signals of various speeds, ranging from 25 to 400 words per minute.
