Description
W tym celu jedno wejscie wzmacniacza 1 polaczone jest bezposrednio z wyjsciem wzmacniacza 3, a drugie wejscie wzmacniacza 1 polaczone jest poprzez wtórnik — separator 4. Natomiast jedno wejscie wzmacniacza 3 jest polaczone bezposrednio z wyjsciem wzmacniacza 1, a drugie wejscie wzmacniacza 3 polaczone jest poprzez wtórnik-separator 2.Dzialanie ukladu jest nastepujace. Sygnal przesylany z punktu A do punktu B jest wzmacniany we wzmacniaczu operacyjnym 1 i przez wtórnik — separator 2 podany do punktu B. Jednoczesnie sygnal z wyjscia wzmacniacza 1 podawany jest w tej samej fazie i amplitudzie na obydwa wejscia wzmacniacza 3, na jedno wejscie bezposrednio, na drugie poprzez wtórnik-separator 2. Wskutek czego wzmocnienie tego sygnalu przez wzmac¬ niacz 3 bedzie równe zeru, przez co uzyskuje sie tlumienie sygnalu zwrotnego. Podobnie sygnal przesylany przez wzmacniacz 3, a nastepnie przez wtórnik 4 jest podawany do punktu A.Analogicznie przez polaczenie wyjscia wzmacniacza 3 z dwoma wejsciami wzmacniacza 1 z jednym bezposrednio, z drugim poprzez wtórnik-separator 4, uzyskuje sie tlumienie sygnalu zwrotnego. PL PLFor this purpose, one input of amplifier 1 is connected directly to the output of amplifier 3, and the other input of amplifier 1 is connected via a repeater - separator 4. However, one input of amplifier 3 is directly connected to the output of amplifier 1, and the second input of amplifier 3 is connected via a repeater -separator 2.Operation of the layout is as follows. The signal sent from point A to point B is amplified in the operational amplifier 1 and by the follower - separator 2 to point B. At the same time, the signal from the output of amplifier 1 is fed in the same phase and amplitude to both inputs of amplifier 3, to one input directly, on the second, through the repeater-separator 2. As a result, the amplification of this signal by the amplifier 3 will be equal to zero, thereby attenuating the feedback signal. Similarly, the signal transmitted by the amplifier 3 and then by the repeater 4 is fed to the point A. Similarly, by connecting the output of the amplifier 3 with two inputs of the amplifier 1 with one directly, with the other via the repeater-separator 4, the return signal is suppressed. PL PL
