Abstract

PURPOSE:To establish the bipolar signal capable of discriminating the data signal, by eliminating the 0 signal continued, making the fourth signal to 1 to the 0 continued four times taking the polarity of the bipolar signal 1 signal before identical to the polarity, and adding 1 immediately after the data signal.
