摘要
为了尽可能减少模数转换器输出的离散数字量与实际测量的模拟量之间存在的偏差,在常用的硬件校正基础上,设计了3种基于不同原理的软件校正方案,并在地震前兆数据采集器的设计中对这3种方案进行了实际应用和验证,取得了较好的校正效果。
In order to reduce the bias and ensure output and analog input, this paper designed three deviations within the acceptable range for ADC kinds of correction schemes of different principle based on software, and practical application of these three schemes were verified not only obtaining good correction results but also providing three alternative design with correction scheme for the earthquake precursor data acquisiton device.
