These calculations might be based on visibility (whether the tag is in the sensor's line of sight), the signal strength, or the amount of time it takes the signal to travel from the tag to the sensor.
这些计算可能基于可见性(标签是否位于传感器的视线中)、信号强度或者信号从标签发送到传感器的时间量。
This paper adopts harmonic choice method to design fluxgate signal processing circuit in allusion to the environment magnetic field strength signal of fluxgate sensor detecting.
针对磁通门传感器检测到的环境磁场强度信号，运用谐波选择法，设计了磁通门信号处理电路。
Then the sensor output signal, amplified by the rectifier to change the coil current until the coil back to bit, its current strength and the object's gravity is called proportional.
这时传感器输出电信号，经整流放大，改变线圈上的电流，直至线圈回位，其电流强度与被称物体的重力成正比。
