Abstract :
It is shown that a wanted a.m. signal may be separated completely from an accompanying unwanted a.m. signal, even when the two carrier frequencies are so close that the sidebands of the signals overlap. The methods involve synchronous demodulation by multiplication by a suitable harmonic series, instead of a single sinusoid.
