Circuit arrangement for pulse signal transmission |
摘要 |
To transmit pulse signals at the same time in in each case opposite directions on telecommunication lines, a circuit arrangement is presented which is capable of evaluating negative potential signals in one direction and positive potential signals in the opposite direction. For this purpose, the transmitting stages are operated at different operating voltages and zenar diodes with different breakdown voltages are allocated to the receiving stages.
