摘要
本文提出了一种用数字相关法测量相位差的方法 ,并加以详细讨论和误差分析。本方法具有精度高、抗干扰能力强、硬件少、适用于低频测量等特点。
A digital correlative method for phase difference measurement is proposed and analyzed. The characters of this method are high precision, strong anti disturbance capability, less requirements to hardware, especially suitable to low frequency measurement, etc.
