How to find resonant frequenfcy?

As the figure, I establish a acoustic emission transducer module, I want to find the resonant frequency, I know I should give a electrical exciation input, but what kind of input should I use? Sien, wvlt, impulse or others?

  • Try, a broadband excitation that encompasses the frequencies of interest. From this an impedance profile can be established from which you can identify resonances by dips and peaks in the magnitude profile.
