Data coding mode: 1 out of 4
The value of 2 bits is represented by the position of one pause. The position of the pause on
1 of 4 successive time periods of 18.88 µs (256/f
successive pairs of bits form a byte, where the least significant pair of bits is transmitted first.
In this case the transmission of one byte takes 302.08 µs and the resulting data rate is
26.48 kbit/s (f
