What do you mean with tune the target frequency? Isn't the
Hello Marco
I not familiar with RFID ASK10% or ASK100%.
(1)
I use usrp -> sinkfft. I can see the wave and tune the target frequency
to 13.56MHz
However, I don't understand the question "why USRP outputs I/Q samples?"
I have to reading more knowledge about communication theory.
(2) You want to
