Communication signal from VCD to LRI64
Communications between the VCD and the LRI64 involves a type of amplitude modulation
called amplitude shift keying (ASK).
The LRI64 only supports the 10% modulation mode specified in ISO 15693 and ISO 18000-
3 Mode 1 standards. Any request that the VCD might send using the 100% modulation
mode, is ignored, and the LRI64 remains in its current state. However, the LRI64 is, in fact,
operational for any degree of modulation index from between 10% and 30%.
The modulation index is defined as (a-b)/(a+b) where a and b are the peak and minimum
signal amplitude, respectively, of the carrier frequency, as shown in
Table 2.
