A method is known for separating radio signals with mutually overlapping spectra ursine double frequency conversion with the use in the first conversion of a synchronous heterodyne, and in the second as a heterodyne, a generator of audio frequency.nThe proposed method of separating one amplitude-modulated signal from a mixture of two amplitude-modulated signals but different carriers, differs from the known ones by the fact that for eliminating the disturbance from the original signal coming from an amplifier of intermediate frequency and representing the sum of two AM oscillations with superposed spectra, but with different carriers, there is separated(with the aid of a very-narrow-hand filter) the carrying oscillation of that AM oscillation which is looked on as the disturbance.
