    Abstract: A device for suppressing a pilot wave in a spectrum of frequencies by subtraction of an auxiliary frequency adjusted in frequency, in phase, and in amplitude to adequate values, used in frequency multiplex telephone transmission systems, containing two pilot frequencies in cases where maintaining either one or several of these frequencies would lead to disturbances.
