Description

эта же разность сигналов, эадержална  и линии задержки 5, котора  также Суммируетс  с входным сигналом, задержанным на строку. Этот суммарный сигнал в сумматоре 4 суммируетс  с сигналом, промодулированным частотным модул тором 2, на входы котор го поступает сигнал с генератора 3 и разность сигналов с вычитател  8. Суммарный сигнал с сумматора 4 поступает на выход устройства.
