carrier suppression
Hi
In UHF RFID 3 modulation types are used from reader to tag:
SSB-ASK
DSB-ASK
PR-ASK
For SSB a carrier is added, but what about DSB-ASK. When a continuous wave is ASK modulated, two sidebands are created. Is the carrier suppressed in this way, since only the two sidebands remain.
And what about PR-ASK, is there also a carrier added to the signal?
Thanks
