A practical approach to applying short time Fourier transform methods in voltammetric investigations

A method for using windowing on a current signal is presented as a means of obtaining amplitude and phase information from electrochemical data transformed from the time domain into the frequency domain. A test method also has been developed to check the reliability of the peak-heights extracted from the data. The limitations have been assessed from both simulations and real experimental data. Additionally, an efficient method for removal of the dc-component in a power-spectrum is presented.
