6.7 BIPOLAR ALTERNATE MARK INVERSION (BIPOLAR AMI)

In the bipolar alternate mark inversion (Bipolar AMI) encoding scheme, 0 is represented by no signal and 1 by positive or negative voltage. Binary 1 bits must alternate in polarity. The advantage of this coding scheme is that if a long string of ones occurs, there will be no loss of synchronization. If synchronization is lost, it is easy to resynchronize at the transition.

In the bipolar AMI encoding scheme, 0 is represented by no signal and 1 by either positive or negative voltage. Binary 1 bits alternate in polarity. Ease of synchronization is the main advantage of this scheme.
