(57) Invenţia se referă la procedee de transmitere<br />
a <strong>in</strong>formaţiei pr<strong>in</strong> semnale analogice şi poate<br />
fi utilizată în <strong>in</strong>terfeţe de comunicaţie a dispozitivelor<br />
electronice distanţate, de exemplu,<br />

receptor, amplasate pe l<strong>in</strong>ia de comunicaţie<br />
asociată cu l<strong>in</strong>ia de curent cont<strong>in</strong>uu, pr<strong>in</strong><br />
variaţia rezistenţei emiţătorului în l<strong>in</strong>ia de<br />
comunicaţie, conectând rezistoarele d<strong>in</strong>tr-un<br />
set de patru rezistoare, trei d<strong>in</strong>tre care, cu<br />

(54) Method for signal transmission through<br />
the direct current l<strong>in</strong>e<br />
(57) The <strong>in</strong>vention relates to methods for <strong>in</strong>formation<br />
transmission via analog signals and can<br />
be used <strong>in</strong> connection <strong>in</strong>terfaces spaced <strong>in</strong><br />
given electronic devices, such as transmitter<br />
and receiver.<br />
The method for signal transmission through<br />
the direct current l<strong>in</strong>e <strong>in</strong>cludes transmission<br />
of the analog signal from a transmitter to a<br />
receiver located on the communication l<strong>in</strong>e,<br />
comb<strong>in</strong>ed with the direct current l<strong>in</strong>e, by the<br />
change of transmitter resistance <strong>in</strong> the communication<br />
l<strong>in</strong>e, connect<strong>in</strong>g the resistors from<br />
a set of four resistors, three of which with<br />
conductances Y s(0), Y s(1), Y s(∞), are reference,<br />
and the fourth, with conductance Y −<br />
<strong>in</strong>formation and is calculated accord<strong>in</strong>g to the<br />
transmitted signal U C, read<strong>in</strong>g by the receiver<br />
of the correspond<strong>in</strong>g current values, calculation<br />
of <strong>in</strong>put conductances of the communication<br />
l<strong>in</strong>e and calculation of the value of the<br />
transmitted signal U C accord<strong>in</strong>g to the correspond<strong>in</strong>g<br />

Novelty of the method consists <strong>in</strong> that as<br />
transmitter is used the reference resistor with<br />
the conductance Y s(0) through the feed circuit<br />
thereof, constantly connected to the direct<br />
current l<strong>in</strong>e, and the rest of resistors<br />
from the set, functionally related to the<br />
transmitter, are connected <strong>in</strong> turn <strong>in</strong> the connect<strong>in</strong>g<br />

resistors and conductance<br />
