Description
лей по значению эквивалента затухани , основанный на предварительном намагннчивании до насыщени магнитной системы телефонного капсюл и последующем частичном размагничивании ее до получени необходимого эквивалента затухани приема, отличающийс тем, что, с целью повышени точности регулировки, значение эквивалента затухани приема определ ют путем измерени полного сопротивлени приbased on the preliminary magnetization before saturation of the magnetic system of the telephone capsule and its subsequent partial demagnetization to obtain the necessary reception attenuation equivalent, characterized in that, in order to improve the accuracy of the adjustment, the value of the reception attenuation is determined by measuring the impedance at
подаче на обмотку телефонного капсюл сигнала фиксированной частоты.filing on the winding of the telephone capsule signal of a fixed frequency.
