FIELD: radio measurements, possible use for building devices for measuring level of frequency distortions introduced by frequency-dependent devices.
SUBSTANCE: method for estimating frequency distortions of quadripole consists of determining amplitude-frequency characteristic of quadripole, when average value of amplitude-frequency characteristic is determined, each value of amplitude-frequency characteristic is reduced by value of average value, then absolute value is isolated in resulting value or the resulting value is raised to second power. Resulting value, being the function of frequency, is integrated within limits of range of researched frequencies, after that the value, resulting from integration, is measured, and the measured value is the estimate of frequency distortions.
EFFECT: increased information capacity of evaluation of frequency distortions introduced by quadripole into original signal.
