x = 0.05 a, y = 0.95 a
m = (a - b) / (a + b).....Modulation index
Note
1. This application specific value must be within this
HITAG S
range, but has to be optimized depending on
transponder coil quality factor and Read performance
requirements. For high quality factor transponder coils,
a lower rise time T
