Сигнал от источника информации станции А поступает на вход блока 1 объединени сигналов, в котором формируетс групповой сигнал. Этот сигнал подаетс на вход модул тора 2, состо щего из генератора поднесущей и смесител . В этом блоке осуществл етс перенос спектра в область несущих частот. Модулированный высокочастотный сигнал с выхода модул i (ЛThe signal from the source of information of station A is fed to the input of signal combiner 1, in which the group signal is formed. This signal is fed to the input of a modulator 2, consisting of a subcarrier generator and a mixer. In this block, the spectrum is transferred to the carrier frequency range.
