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. The results of the analysis for two independent objects included in different combinations showed that the proposed model fully corresponds to the measured data. The above approach can be useful in the practical application of noise methods in electrochemistry.
