Abstract

Заявлены устройство и способ для измерения индуктивности проводного контура (20) без прямого сравнения с какой-либо конкретной постоянной времени или частотой. Низкочастотный шум, наведенный в проводном контуре (20), компенсируется в схеме (24а, 24b) детектора, а перекрестные помехи между множеством соседних проводных контуров (20а, 20b) нейтрализуются с использованием пассивных трансформаторов (22). Новые конфигурации проводных контуров (20а, 20b) используют анализ несущей, модулированной изменением магнитной проницаемости, для формирования обладающих воспроизводимостью индуктивных характеристик с использованием невстраиваемых или встраиваемых на небольшую глубину установок.Международная заявка была опубликована вместе с отчетом о международном поиске.
