SIGNAL TRANSFER METHOD BETWEEN MASTER AND SLAVE DEVICES Russian patent published in 2021 - IPC H04B3/04 H04R3/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to radio engineering. The effect is achieved by detecting the connection between one of the contacts of the second kind of the master device and the slave device by detecting the voltage on such a contact of the second kind, determining the contact of the first kind of the master device to which the slave device is connected by establishing different voltages on the contacts of the first kind, and determination of the voltage on the contact of the second kind; changing the voltage between the contact of the first kind, to which the slave device is connected, and the internal power line connected through a resistance to the contact of the second kind, to which the slave device is connected; shaping a signal on the slave device by changing the resistance between the contacts connected to the master device; receiving a signal at the master by measuring the voltage at the second-order contact to which the slave is connected.

EFFECT: simplification of circuitry implementation of signal transmission.
