7.4
Data are transmitted to the transponder using Amplitude
Shift Keying (ASK) modulation with a modulation index of
100 %. When the field is switched off, the physical state is
named low field, otherwise high field.
7.4.1
Binary Pulse Length Coding (BPLC) is used to encode the
data stream.
All coded data Bits and the end of frame (EOF) condition
start with a low field of length Tg.
