Abstract
Изобретение относитс к радиотехнике и св зи. Цель изобретени - повышение качества воспроизводимых сигналов. Стереоприемник частотно-модулированных сигналов содержит высокочастотный блок 1, частотный детектор 2, состо щий из измерител 3 периода, блока 4 управлени и блока 5 посто нной пам ти, стереодекодер 6, состо щий из блока 7 выделени поднесущей частоты, стереодетектора 8, блока 9 стереоавтоматики и фильтров 10 и 11 нижних частот, а также переменный резистор 12 и усилители 13 и 14 низкой частоты правого и левого каналов. Цель достигаетс путем обеспечени повышени стабильности обнаружени поднесущей частоты. 3 ил.The invention relates to radio engineering and communications. The purpose of the invention is to improve the quality of reproducible signals. The stereo receiver of frequency-modulated signals contains a high-frequency unit 1, a frequency detector 2 consisting of a 3 period meter, a control unit 4 and a permanent memory unit 5, a stereo decoder 6 consisting of a subcarrier allocation unit 7, a stereo detector 8, a stereo unit 9 and low-pass filters 10 and 11, as well as a variable resistor 12 and low-frequency amplifiers 13 and 14 of the right and left channels. The goal is achieved by providing increased stability in detecting the subcarrier frequency. 3 il.
