Description

Коэффициенты .делеаи  Ki и Kz делителей 3 и 7 частоты выбраны такими,.чтобы частоты по  вленй  йЖульсбв выходах были равны, когда f/i Удф; гдеThe coefficients of the Ki and Kz divisions of the 3 and 7 frequencies are chosen such that the frequencies of the outputs in the outputs are equal when f / i Udf; Where

f/i - величина порогового уровн  первого порогового блока; t/эф - измеренное значение помехи. .,f / i is the threshold level value of the first threshold unit; t / eff - measured interference value. .

Очетчик 4 подсчитывает разлость выходных Импульсов делителей и 7 частоты и через ЦАП 8 у пр|авл ет пороговым уровнем U таким образом, -чтобы U . Код на выходе счетчика 4 и напр жение на входе ЦАП 8 соответствуют значению эффективного напр жени  помехи.The meter 4 calculates the divisibility of the output impulses of the dividers and 7 frequencies and through the DAC 8 at the pr | avlet threshold level U in such a way that U. The code at the output of the counter 4 and the voltage at the input of the D / A converter 8 correspond to the value of the effective interference voltage.
