Applications of the FFT in Electrochemistry
Most modern electroanalytical techniques are basically electrochemical relaxation measurements (ERM), in which one observes a time-varying response from some type of electrochemical cell to an applied perturbation such as current, potential, or charge. The observed relationship between the response and the perturbation is known as the transfer function and provides analytical data, kinetic information, and/or mechanistic information on a variety of processes that can occur in the electrode, in the electrolyte bulk, or in the interfacial regions. Perhaps the most common experiment is one in which a cell voltage perturbation is created and the cell current response is measured. Typical techniques that fall into this category are DC, AC, and pulse polarography, linear sweep and triangular wave voltammetry, and potential step chronoamperometry.
