BIT REPRESENTATION AND CODING
Data bits are encoded using Manchester coding,
according to the following schemes.
For the low data rate the same subcarrier frequen-
cy or frequencies are used, in this case the num-
ber of pulses shall be multiplied by 4 and all times
will increase by this factor.
Bit Coding Using One Subcarrier
High Data Rate.
A logic 0 starts with 8 pulses of
423.75 kHz (f
C
/32) followed by an unmodulated
time of 18,88μs as shown in Figure 12.

A logic 1 starts with an unmodulated time of
18.88 μs followed by 8 pulses of 423.75 kHz (f
