For a given proportion p (where p is the confidence level), a confidence interval for a population parameter is an interval that is calculated from a random sample of an underlying population such that, if the sampling was repeated numerous times and the confidence interval recalculated from each sample according to the same method, a proportion p of the confidence intervals would contain the population parameter in question.

对于一个比例 P而言，一个群体参数的置信区间中的区间是由一个基础群体的随意样本计算出的，假如样本被重复了无数次，置信区间也根据每个样本，以同样的方法重新计算，那么这个置信区间中的比例 P 将要重新定论。

When realizing on hardware, for an M×N UFPA, at any sampling time, a shift-register is used to store M data which is before the current sample data and the shift-register′s output is updated with the data which is at the same column while the upper row. Meanwhile, a common register is used to store the data which is at the same row while the previous column.

在硬件实现阶段，对于M×N的UFPA器件，在任意采样时刻，利用移位寄存器保存当前采样点之前的M个响应值，使其输出可实时更新为与采样点同列的上一个数据；同时，利用一般的寄存器实时保存与采样点同行的前一个数据，采用同帧行列间内插法实现无效像元的实时补偿。
