Data coding mode: 1 out of 4
The value of two 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
Four 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 Kbits/s (f
