Abstract

The invention involves a signal system which is then adapted to digital signals. And which include transmitter (70), receiver (80) and connection Which connect the transmitter To the receiver The transmitter will include an output bumper (71 ') which contains a transistor. Is the least (71a) connected to the lowest level of The source voltage (72), such as with the `` 0 '' terminal or the earth terminal, driving or controlling the transistor (71a) responding to the received control signal (74) will cause the Switches from a high impedance state to a low impedance state. Which feature Of resistance Or at the very least The pre-determined resistance of the type used to generate the conductive output signal (90). The first transistor (71a) of the two connected (71a, 71b) is connected to the level. The minimum of the source voltage For example, the '' 0 '' terminal or earth terminal where another transistor (71b) is connected to the source voltage (72), the connecting conductor (90a) on the part where the signal carrier is sent. To be connected between transistors (71a, 71b), transistors (71a, 71b) are placed in different states simultaneously and in low impedance states where the impedance is applied. On the impedance (resistance) of the connection
