1. A method of highly time resolved impedance spectroscopy comprising:

  • generating an a.c. voltage perturbation signal and applying it to a system;

    recording the a.c. voltage perturbation signal and a current signal produced in response to the perturbation signal; and

    processing the recorded signals using a non-stationary time to frequency transformation.
