In this dissertation, digital lock-in detection techniques under integer period sampling and non-integer period sampling are separately investigated (1) Under integer period sampling, digital signal sequence is acquired through sampling the measured signal, but digital reference sequence is acquired through mathematical operation, then digital lock-in detection can be realized by calculating crosscorrelation function of digital signal sequence and digital reference sequence Harmonic measure is also analyzed, and a method of measuring harmonic of a periodic signal under aliasing is put forward.

本文对使用采样ADC把模拟信号转换为数字信号并通过计算数字信号的相关函数来实现锁定检测的技术进行了研究，在此基础上设计了一个多功能的数字LIA并在一些科学实验中进行了应用。本文对整周期采样和非整周期采样时的数字锁定检测技术分别进行了研究。(1)在整周期采样时，对被测信号进行采样得到信号序列，而参考序列由数学运算得到，通过计算信号序列和参考序列的互相关函数就可实现锁定检测。

By constructing the piecewise linear function from samples, it is able to approximate the measured metric more precisely. Compared with current popular sampling algorithms, FASM algorithm can provide more precise estimation of metric under the same samples. In the condition of retaining the same approximation errors, our adaptive sampling methodology only requires fewer samples, which will save sampling costs considerably during sampling process.

与当前常用的抽样算法相比，在采集相同的样本数量情况下，本文的拟合模型对指标进行的估计更准确、稳定；而在保持相同的拟合误差时，自适应抽样算法则可显著减少所需采集的样本数量，节约数据采集过程的代价。
