Description

леграфного приемника только такую последовательность имнульсов, котора  св зана определенным соотношением с их длительностью .a damages receiver is only such a sequence of pulses, which is related to a certain ratio with their duration.

При ностуилении на вход телеграфного приемника помех из канала св зи указанное соотношение измен етс , а результат изменени  регистрируетс  блоком 4 отсчета времени и через логический блок 5 поступает на вход накопител  6, который закрывает своим сигналом выход приемника на все врем  действи  помехи.When notifications are made to the input of the telegraph receiver of interference from the communication channel, this ratio changes, and the result of the change is recorded by the time counting unit 4 and through the logic unit 5 is fed to the input of the accumulator 6, which closes the receiver output with its signal for the duration of the interference.
