HDB3 PATTERNS
E = indicates even number of pulses since last violation (V)
OD = indicates odd number of pulses since last violation (V)
V = intentional violation of alternating plus and minus pulses used for 1’s
B = pulse that follows the normal alternating Bipolar coding scheme
•
four zeros are replaced with B00V or 000V; the substitution choice is made so that the number of pulses between
violations (V’s) is odd; note that sequential violations are of opposite polarity so the net charge on the transmission
medium is zero.
