正弦交流采样理论误差的估计

交流采样技术在多种智能化仪表中得到广泛应用。它的主要思想就是在一个周期内用若干个交流信号瞬时值描述该交流信号波形，并计算出有效值及其它有关参数。一个周期内对交流信号来样次数与由采样次数所带来的误差关系。对比从理论上作了探讨。

Theoretical error estimation of sine AC sampling

The AC sampling technology has been widely applied in lots of intelligent instruments. Its main ideas are that the AC waves are described through some AC instantaneous values in a period, and then RMS values and other con- cerned parameters are worked out. The relationship between the sampling number in a given period and its following computational errors is discussed.
