FIELD: physics.
SUBSTANCE: invention concerns radio measurement field and is designed for integral estimation of frequency distortion evoked by in random baseband signal four-pole circuits. The device includes two wave analysers and correlation rate indicator. The process involves measurement of correlation rates for input and output signal spectra. A value of spectra correlation rate is the sought frequency distortion estimation.
EFFECT: simplification of technical solutions owing to exclusion of spectrum rating.
