SOF When Using Two Subcarriers

High Data Rate. SOF comprises 3 parts: (see

Figure 22)

– 27 pulses of 484.28 kHz (fc/28),

– 24 pulses of 423.75 kHz (fc/32),

– a logic 1 which starts with 9 pulses of

484.28 kHz followed by 8 pulses of 423.75 kHz.

Low Data Rate. SOF comprises 3 parts: (see

Figure 23)

– 108 pulses of 484.28 kHz (fc/28),

– 96 pulses of 423.75 kHz (fc/32),

– a logic 1 which starts with 36 pulses of

484.28 kHz followed by 32 pulses of

423.75 kHz.
