摘要
建立了Ａ／Ｄ转换器的传递函数及误差的数学模型，在该数学模型的基础上，仿真分析了模拟数字混合采样算法功率测量各种情况下的误差，使对该种采样方法的误差特性有了深入全面的认识。本文的结论对设计该类仪器的误差估计具有指导作用。
The transfer function and the mathematical model of A/D converter are established. Based on this model, the errors of the analogue digital mixed sampling algorithm on power measurement are analyzed by computer simulation. Several important conclusions are recognized on the error characters of this type of sampling method. These conclusions are usefull for the error estimation on designing this type of instrument.
