In the line coding scheme 2B1Q, the r is equal to
Hint: r =
the number of data elements/the number of signal elements. To line encode
00 in 2B1Q, we need to find out the polarity of the previous signal element.
Assume that the previous signal level is positive, then 00 is encoded as
and 10 is encoded as
