Notes
1. Modulation type is Amplitude Shift Keying (ASK). A modulation ratio of 100% means the carrier is blanked
completely, the information is located in the intervals between the pauses.
2. Modulation type is Amplitude Shift Keying (ASK). The modulation ratio depends on the distance between
transponder and reader module.
