Abstract

Безтрансформаторна диференційна система містить диференційний підсилювач, перший дріт вихідного кола чотиридротяного тракту, перший та другий дроти вхідного кола чотиридротяного тракту, перші та другі повні балансні опори, перший та другий дроти дводротяної лінії. З метою забезпечення симетрії дводротяного тракту перший дріт дводротяного тракту через перший резистор з'єднано з інвертуючим входом, а другий дріт дводротяного тракту через другий резистор – з неінвертуючим входом диференційного підсилювача.
