we used a RC circuit for measuring resonance frequency of a piezoelectric. And each time, we changed the frequency domain of the input. The impedance model, in terms of frequency, indicates that the peaks are shifted by varying the frequency of the applied action. Is it rational? Why? What is the best method for measuring piezoelectric resonance frequency?
