Beschreibung
Zusammenfassung:	The proposed device for isolating one of two signals with different frequencies contains, in each channel, a resonator adjusted to the frequency of the signal to be isolated, a frequency detector, a comparator, and additionally, a resistive voltage divider. The output of the resonator is connected to the input of the frequency detector. The disable input of the comparator of the first channel is connected to the output of the frequency detector of the second channel and, via the voltage divider of the second channel, is connected to the enable input of this comparator. The disable input of thecomparator of the second channel is connected to the output of the frequency detector of the first channel and, via the voltage divider of the first channel, is connected to the enable input of this comparator.
