所有物理量的测量，最后都是以数值形式给出结果，本文所述的数字化测量，则是特指使用A／D转换原理，对模拟物理量进行的测量。其主要特征是以具有量化特征的过程和结果描述具有连续特征的物理量。这样的测量，是伴随着A／D转换器的诞生而产生的，其目的最初也仅是为了提高测
The measurement of all physical quantities, the final results are given in numerical form, digital measurements described in this article, it refers specifically to the use of A / D conversion principle, the measurement of the simulated physical quantities. Its main feature is to describe the physical quantities with continuous features based on the process and result with quantitative features. This measurement is accompanied by the birth of the A / D converter and its purpose was originally only to improve the measurement
