26. What is the result of scrambling the sequence 11100000000000using one of the
following scrambling techniques? Assume that the last non-zerosignal level has
been positive.
B8ZS
I understand the basic premises of this algorithm 000VB0VB but notsure how to apply it to this problem. There are 14 '1s 0s'B8ZS requires 8... unless it only applies to the 0's. My bookis pretty much useless at explaining this to be usedpractically.

I don't need solution worked just the logic. Thanks inadvance for any help - resources

Explanation / Answer

Bipolar with eight-Zero Substitution (B8ZS)replaces each string of 8 consecutive zeros with the specialpattern "000VB0VB". Depending on the polarity of the preceding mark, that could be000+0+ or000+0+. Here we have 11100000000000...there are 8 consecutive zeros in thegiven pattern 11100000000000 will be converted to111000+-0-+000 or111000-+0+-000 depending upon the polarity
