Description
Предлагаетс схема, сшшчающа ллл тию токов помех иа работу приемного телеграфного реле.A scheme is proposed that compares the noise currents and the operation of the receiving telegraph relay.

The scheme can be implemented independently of any other devices that reduce interference, and therefore, it is important that dunlex communications are stable.
На . 1-4 приведена принншшальпа схема включени выпр мительных элементов в дополнительную обмотку реле и диаграммы TOKoii в DToii обмотке.On . Figures 1–4 show the installation of the rectifying elements in the additional relay coil and TOKoii diagrams in the DToii winding.

Вследствне этого ток в донолпнтельио обмотке мал (крива I на фиг. 4) и замедлительиое действие се ничтонхно. При наличии расстройки балаисов, особеипо емкостнойA complete winding of the III relay (FNG-1) includes a circuit K, which is not solid rectifiers Ki and lu (kunrox), connected as shown in the diagram (Fig. 2). Therefore, this department depends on the panel, iri. — gozhepiiy to its clamps. From a magnification: the voltage of the voltage is the general sonotically contour of the circuit and the more painful it is than its longer resistance. The dependence of the resistance of the contour RK on the pan U on the terminals is shown in the fng. 3A signal coming from the line, which is a form of current creep, induces a small electromotive force in the additional winding of the linear relay (ed-s.). Owing to this, the current in the donolpnelio winding is small (curve I in Fig. 4) and the moderating effect is nothing. In the presence of Balais detuning, special capacitive
