FIELD: measurement technology. ^ SUBSTANCE: voltage is formed which has instant values to define values of standardized amplitude-frequency characteristic of two-port network. Then the voltage is changed by the unity. Absolute value of voltage is selected from formed voltage and integrated within the limits of operation of this voltage. Quantitative evaluation criterion of frequency distortions has to be area of frequency distortions achieved as a result of integration. Method can be used for measuring level of frequency distortions induced by two-port networks. ^ EFFECT: improved reliability of evaluation of frequency distortions. ^ 2 cl, 1 dwg |
