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 the ISO15693 standard. Any re-
quest that the VCD might send using the 100%
modulation mode, is ignored, and the LRI64 re-
mains 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
Figure 4.
