Abstract
In a data bus with m data bits, electromagnetic interference is produced by polarity switching the data on that data bus. When two consecutive data items result in a change of over half of the data bits, the polarity of the second data item is switched, and a polarity signal is correspondingly switched on the data bus. When the data is received, it is restored to its original polarity by adjusting the polarity of the received data according to the signal on the polarity line. In this way, the total number of bit transitions between any two data items is reduced to a maximum of m/2.
