摘要:
A duty cycle is used in conjunction with a powered oscillator to electronically reduce the current draw by reducing the average current and thus reducing the sensor radiated emissions without altering an inductive position sensor. The duty cycle and the switching of the oscillation drive enable an on and an off cycling of the inductive position sensor such that an oversampling may occur without altering the hardware, but providing the improvements. As such, the inductive position sensor may only have an oscillation signal long enough to capture a stable sample and remain off for the duration of the sampling period. As such, a reduction in radiated emissions is achieved.
