     Erfindungsgemäss werden   nun Widerstände W und Kapazität C derart bemessen, dass die Ab-   klingzeit.   d. h. die Zeit, in welcher der Gleichstrom auf den e-ten Teil abfällt, die Dauer eines Signales übertrifft. 



   Soll die Abklingzeit eine Sekunde betragen, was bei normaler Telegraphiergeschwindigkeit ausreichend erscheint, so ergibt die Rechnung als erforderliche Werte für die Kapazität   ('= 1 Mikrofarad   und für den Widerstand W = 1 Megohm,
Die sich als erforderlich   ergebenden Widerstände und Kapazitäten   sind   um   ein Vielfaches grösser als die bei der bekannten Schaltung gewählten. Bei dieser wird danach getrachtet. den Betrag der Wider-

 EMI2.1
 



     According to the invention, resistors W and capacitance C are now dimensioned such that the decay time. d. H. the time in which the direct current drops to the e-th part exceeds the duration of a signal.



   If the decay time is to be one second, which seems sufficient at normal telegraphing speed, the calculation results in the required values for the capacitance ('= 1 microfarad and for the resistance W = 1 megohm,
The resistances and capacitances that are required are many times greater than those selected in the known circuit. This is what is sought after. the amount of the
