MULTIPLEXING SCHEME AND MOBILE TERMINAL Russian patent published in 2021 - IPC G06F13/40 

FIELD: communication technology.

SUBSTANCE: invention relates to the field of electronic and communication technologies. The multiplexing circuit contains three switching circuits. The first switching circuit transmits the audio signal of the right audio channel provided by the transmission output of the right audio channel to the transmission output of the first signal. The second switching circuit transmits the audio signal of the left audio channel provided by the output of the transmission of the left audio channel to the transmission output of the second signal. The signal transmission between the transmission output of the first signal and the first output pin and signal transmission between the transmission pin of the second signal and the second output pin are implemented using the third switching circuit. The first switching circuit includes the first transistor and the first DC voltage control circuit. The second switching circuit includes a second transistor and a second DC voltage control circuit.

EFFECT: simplification of the design of the switching circuit.
