The term antiresonance is used when the reactive part of the impedance of a EM system is very high.
Material coefficients, which will be compared, are calculated indirectly from the size, density and resonance frequency and antiresonance frequency of PZT ceramics.

Programmable motor current and microstepping selection make systems based on these products very easy to use and an advanced antiresonance feature provides midrange stability.
Thanks to this, there is no problem with a possible confusion of the resonance and antiresonance frequency measuring double peak during this measurement, this problem can be noticed in devices, which do no allow displaying the characteristics directly during the measurements.
The attenuation is highest at the antiresonances of the plenum chamber, while the plenum is acoustically transparent to the HVAC system at the resonances of the plenum chamber.
