<p>The method involves determining output of an activation signal, in which a response threshold (Pchip) is reached. Radio frequency identification-chips (1) with complex valued verification impedance with a known real part and a known imaginary part are connected. An output of another activation signal is determined, where another response threshold is achieved in the latter activation signal. Impedance (Zchip) of the chips is calculated from the real part, another real part, imaginary part and another imaginary part of the verification impedance and another verification impedance. An independent claim is also included for an arrangement for implementing the method for measuring technical determination of impedance of the passive radio frequency identification-chip.</p> |
