Method and apparatus for active isolation in inductive loop detectors |
摘要 |
An oscillator circuit for use with a wire-loop inductive sensor and method for use. The oscillator circuit highly attenuates common-mode noise detected by the wire-loop and differential noise from both ambient and crosstalk sources are filtered by active isolation.
