Description

Verfahren zum Entkoppeln von Stromkreisen für bestimmte Frequenzen Bei den verschiedenartigsten Anwendungen der elektrischen Schwingungen ist es oft erwünscht, zwei miteinander gekoppelte Stromkreise für bestimmte Frequenzen so zu entkoppeln, daß keine Energieübertragung von dem einen auf den. andern Kreis stattfindet. Es ist bekannt, zu diesem Zwecke aus hintereinandergeschalteter Kapazität und Selbstinduktion bestehende Kopplungsglieder anzuwenden.Procedure for decoupling circuits for specific frequencies It is often the case with the most diverse applications of electrical oscillations desirable to have two circuits coupled together for certain frequencies decouple that no energy transfer from one to the other. another circle takes place. For this purpose, it is known that capacitance and self-induction are connected in series apply existing coupling links.

Gemäß der Erfindung wird dem aus Kapazität und Selbstinduktion in Hintereinanderschaltung bestehenden Glied eire Ohmscher Widerstand parallel geschaltet. Hierdurch bleibt die Resonanzkurve der- beiden. Schwingungskreise im wesentlichen erhalten, In der Abb, i ist ein Ausführungsbeispiel einer derartigen Entkopplung für zwei Schwingungskreise dargestellt, Der aus dem Ohmschen Widerstand i, der Kapazität 2 und der Selbstinduktion g bestehende Schwingungskreis ist mit einem ebensolchen aus dem Ohmschen Widerstand q., der Kapazität 5 und der Selbstinduktion 6 bestehenden Schwingungskreis durch das aus der Kapazität 7 und der Selbstinduktion 8 bestehende Glied und dem Ohmschen Widerstandg gekoppelt. Dieser Ohmsche Widerstand stellt eine für alle Frequenzen gleichbleibende Kopplung der beiden Schwingungskreise dar, während das aus Kapazität und Selbstinduktion bestehende Glied bei allen außerhälb seines Resonanzbereiches liegenden Frequenzen einen so hohen Widerstand hat, daß es gegenüber dem Ohmschen Widerstand gar nicht in Betracht kommt, während im Falle der Resonanz das Verhältnis gerade umgekehrt ist.According to the invention, the capacitance and self-induction in Series connection existing members eire ohmic resistance connected in parallel. As a result, the resonance curve of both remains. Oscillation circles essentially In Fig, i is an embodiment of such a decoupling shown for two oscillating circuits, the one from the ohmic resistance i, the capacitance 2 and the self-induction g existing oscillation circuit is with such a consisting of the ohmic resistance q., the capacitance 5 and the self-induction 6 Oscillation circuit through the one consisting of the capacity 7 and the self-induction 8 Member and the ohmic resistance. This ohmic resistance represents a for all frequencies constant coupling of the two oscillation circles, while the link consisting of capacity and self-induction in all outside his own Frequencies lying in the resonance range has such a high resistance that it is opposite the ohmic resistance is out of the question, while in the case of resonance the relationship is just the opposite.

Für die beiden Schwingungskreise erhält man eine Resonanzkurve der in Abb.2 gezeichneten Art, .die, ohne daß sie durch das Entkopplungsglied 7 und 8 in ihrer Form wesentlich verzerrt wird, für die Frequenz, auf die das aus Kapazität und Selbstinduktion. bestehende Glied abgestimmt ist, eine Nullstelle ja hat,. Durch Anordnen mehrerer abgestimmter Glieder lassen sich noch beliebig weitere Nullstellen in. der Resonanzkurve schaffen.A resonance curve is obtained for the two oscillation circles in Fig.2 drawn type, .the, without it being through the decoupling member 7 and 8 is significantly distorted in its form, for the frequency to which the out capacitance and self-induction. existing link is matched, has a zero point yes. By Arranging several coordinated links can be any further zeros in. create the resonance curve.
