EOF When Using Two Subcarriers
High Data Rate. EOF comprises 3 parts: (see
Figure 26)
– a logic 0 which starts with 8 pulses of
423.75 kHz followed by 9 pulses of 484.28 kHz,
– 24 pulses of 423.75 kHz (fc/32),
– 27 pulses of 484.28 kHz (fc/28).
Low Data Rate. EOF comprises 3 parts: (see
Figure 27)
– a logic 0 which starts with 32 pulses of
423.75 kHz followed by 36 pulses of
484.28 kHz,
– 96 pulses of 423.75 kHz (fc/32),
– 108 pulses of 484.28 kHz (fc/28).
