Abstract

Методът и системата намират приложение в съобщителната техника. При тях е възможно използване на еднолентов сигнал в дълговълновия обхват. Съгласно метода подносещата честота се модулира квадратурно двулентово с данните. От модулирания сигнал се изготвя еднолентов сигнал с остатъчен сигнал с носещачестота, който се преобразува в дълговълновия обхват чрез смесване с честотата на генератор, след което се излъчва. Схемата откъм предавателната страна съдържа кодер (2), честотен преобразувател (2, 3), еднолентов филтър (5), честотен преобразувателв дълговълновия обхват (6, 7) и предавател (8), аоткъм приемната страна - усилвател (14), генератор(15), смесител (16), лентов филтър (17) и демодулатор (18), който може да е синхронен или асинхронен.
