See Figure 27, "Data coding example," on page 233
for an illustration of the transmit and receive coding
methods.
transition at the beginning of the
bit-time; the level that appears during the
previous cell us reversed. A 1 is represented by
the absence of a transition at the beginning of
the bit cell.
the beginning of the bit-time followed by
another transition in the middle of the bit-time.
A 0 is represented by a transition only at the
beginning of the bit-time.
the beginning of the bit-time followed by
another transition in the middle of the bit-time.
A 0 is represented by a transition only at the
beginning of the bit-time.
level during the first half of the bit-time and a
low level during the second half of the bit-time.
A 0 is represented by a low level during the first
half of the bit-time and a high level during the
second half of the bit-time.
represented by a transition at the center of the
bit-time, with the opposite polarity from the
transition at the center of the preceding bit-time.
A 0 is represented by a transition at the center of
the bit-time with the same polarity as the
transition at the center of the preceding bit-time.
In both cases, there are transitions at the
beginning of the bit-time to set up the level
required to make the correct center transition.
