sampled threshold

By setting a effective threshold for resolver transmitter signal, which is sampled by a A/ D and is sent to Digital Signal Processor ( DSP), noise in the resolver transmitter signal is filtered, the stabilization of the algorithm in the different temperature is verified.

通过对旋转变压器信号设置一个处理的有效阈值，A/D采样后送往中央处理单元DSP的旋转变压器信号经过一个滤波环节，可以有效地滤除信号中的噪声，简化了旋转变压器信号处理的算法。
