Stochastic Errors in Frequency Domain

The magnitude of the stocheistic errors in impedance measurements depends on the selection of experimental parameters as detailed in Chapter 8. The simulation results described by Carson et a 00,25i,255 particular provide insight into differences between commonly used impedance instrumentation, including methods based on Fourier analysis and on phase-sensitive detection.  

Some general properties for stochastic errors have been established for impedance measurements through experimental observation and simulations. The results described here correspond to additive time-domain errors. The comparison between simulations and experimental results obtained via Fourier analysis supports the suggestion that the nature of experimental time-domain errors is likely to be additive rather than proportional
