摘要
在所用模数（Ａ／Ｄ）转换器的满量程转换电压和最小分辨电压都以确定的情况下，对于被测信号的特定幅值，如何确定最终数字化结果的有效数字位数，作者在实际工作中总结出规律性，具有一定的普遍性和指导意义。
When the full measuring range switching voltage and minimum resolving voltage of the analog digit converter (A/D) being used has been defined, and as far as the specified range of the signal being tested is concerned, the writer, from his working experiences, has ascertained the regularity of how to define the significant digit capacity of the ultimate digitized results which is of universality and great guiding significance.
