The study relates to the general problem of noise research in electrochemistry. The special issue of recognition of a weak signal against the background of equipment noise was considered . Chemical power sources were used as an object. The measurement results were analyzed using a standard model including the noise voltage and noise current of the equipment. The criterion of correctness of the model was compliance with the quadratic law of addition of components of a random noise signal.

Possibilities for increasing efficiency of impedance spectral measurements are investigated. It is shown that for determination of linear electrochemical impedance a linearly changing input signal is preferable, and for the quantitative estimation of non-linearity of electrochemical impedance as an input signal it is expedient to use the cosine electric beats. The constructive diagrams of generators of such signals are offered.
