Abstract
This paper examines the various techniques that may be used to analyse electrochemical noise data, and explores the theoretical basis of the more important methods. Methods considered include: ○ Time domain analysis methods - including the direct measurement of the properties of transients from the time record. ○ Statistical methods - including the measurement of the mean, standard deviation/variance, noise resistance, coefficient of variation, localisation parameter and other statistical parameters. ○ Frequency domain analysis methods - including spectral estimation using various methods, including MEM and FFT, the determination of noise impedance, the determination of bispectra and wavelet analysis. ○ Discriminant analysis - this is a general method for determining the ability of a particular measurement to discriminate between alternative behaviours, and its application to electrochemical noise analysis is indicated.
