Усилители с переменным КУ

Усилители с переменным коэффициентом усиления (VGA, variable gain amplifiers) применяются в разнообразных задачах удаленных измерений и оборудовании связи более полувека. Переменное усиление используется для улучшения динамических характеристик в различных областях, от систем ультразвукового диапазона, радиолокаторов, лазерных локаторов до беспроводной связи, и даже анализа речи.
