Abstract
Adaptive transmission of a tag activation signal and detection of a tag. By monitoring the effects of a load on a tag activation signal, a signal analyzer adjusts the transmission waveform from which the signal is generated so that the next tag activation signal transmitted into the load more closely corresponds to a desired activation signal.
