FIELD: radio engineering, possible use for constructing means for automatic control over signal spectrum shape, for example, automatic adjustment of timbre of sound in audio equipment by means of equalizer.
SUBSTANCE: invention is based on comparison of spectrums of original and standard signals and further on correction of relations between spectrum components of original spectrum with use of comparison results.
EFFECT: stabilization of signal spectrum by means of automatic adaptive frequency correction in accordance to arbitrarily set requirements.
