ABSTRACT:
A method is described for transmitting signals on a pair of lines, whereby the signals pass alternately from a low level to a high level. The signals on one line of the pair transmit a complementary level of signals to the other line of the pair, whereby signal drivers are used in a manner to affect an exchange in the levels of the transmitted signals. First, the signal drivers that send complementary levels of signals to the two lines are isolated from the lines. Second, the lines are short-circuited so that an identical intermediary potential between the low-level and the high-level signal, is applied. Third, the short-circuit is removed and the signal drivers are connected so that inversely complementary levels of signals can be sent to both lines.
