Impedance Measurement Techniques: Sine Correlation
By B Sayers and A Hinton
Keywords:
Frequency response analyzer (FRA), single sine correlation, harmonic rejection, and noise rejection, Electrochemistry
An overview of the single sine correlation technique is presented. The method employed by Solartron FRAs is the most accurate impedance measuring technique available since it simultaneously rejects harmonics and with appropriate integration periods can even detect signals that are buried in the noise.
