[Method of determining system errors due to the quality of the electronic filters in the spectral analysis of noise vibration].

A method to determine systematic errors, conditioned by the extreme degree of fading out, beyond the permeability band of electric filters used in noise and vibrations' spectral analysis, is suggested. The obtained formulas for the active filters of the noise-measuring apparatus PSI-202, making part of the hygiene network equipment throughout the country, are tabulated and thus prompt determination of the respective systematic error is rendered possible.
