Abstract

Спосіб керування частотою багатоканального передавача включає генерування опірної частоти та її подачу на термостабільний частотний дискримінатор, від котрого подають напругу постійного струму послідовно на множинність окремих генераторів, отримуючи від них окремі сигнали, котрі підсумовують у вихідний сигнал, що має багатоканальну проміжну частоту.
