摘要
本文对采样字长短而采样精度要求高的采样系统，提出了利用噪声以采样速度换取采样精度的滤波方法．实践证明：这种采样系统价格低精度极高．
This paper puts forward a high accuracy filtering method which can transform the sampling speed into high sampling accuracy using noise.This method is very useful for some sampling systems in which word size of the sampling is somewhat short but the sampling accuracy must be very high.Practice proves that the cost is low and the accuracy is very high.In the control system of digital manipulating instrument of aircraft,this filtering method has obtained satisfactory results.
