Egad. Calling it antiresonance is asking for (communications) trouble,
since not eveyone uses the same terms. Just call it "half-wave
resonance" and "full-wave resonance". I don't think I've EVER heard
anyone call a parallel-tuned circuit "anti-resonant." I do regularly
hear people distinguish between series and parallel resonance, however.
I'm not likely to soon adopt "antiresonance" for either condition, as
it sounds way too much like something opposing resonance.
