一种提高A/D系统分辨率的通用方法

A METHOD FOR IMPROVING THE RESOLUTION OF A/D CONVERSION SYSTEMS

提出了在量化单位受系统噪声限制的条件下 ,提高A/D系统分辨率的一种有效方法—梯度均值法 .对梯度均值法的工作原理给出了严格的数学论证 ,并与普通的统计均值法进行了性能对比分析 .该方法的原理可推广应用于任一量化系统 ,在达到相同分辨率的条件下 ,与普通均值法相比响应速度大为提高 .

An universal method for improving the resolution of A/D conversion system is proposed.The general principle is described with a rigorous mathematical treatment.For getting same resolution,the A/D conversion systems based on the proposed method can run at much higher conversion speed than the ones based on the normal mean value procedures.
