摘要:
本文提出了一种“延伸DFT”理论,并建立了一种检测交流信号相位的数学模型,为利用微机精密测量相位提供了一种有效的算法。它不同于一般数字式相位计所利用的信号“过零点”测量相位法,因而可以获得更高的测量精度.文中给出了计算机仿真运算的结果。为了满足标准相位计高精度测量要求,还给出了进一步提高测量精度的修正公式。
Abstract:
Proposes an extented DFT theory, with which a mathematical model for measuring the phases of ac. signal is presented and a precise measurement method is obtained. It is different from the conventional method used in digital phase-meters. The measuring error of computer simulation is given. In order to satisfy the demand of standard phase-meters, a modification formula is suggested.
