测量相位差并用LCD显示。从信号源接入两路信号,经过AD1和AD2转换后，送入FPGA中。
在FPGA中，使用双值法整形，得到两路标准的方波，然后测出两路信号的时差Δt，以及信号的周期T，
并计算相位差（ΔΦ=Δt/T*360°）。并送入1602中显示。经测试，其测相误差小于1 。-Measured phase difference and with LCD display. Two-way access from the source signal, converted by AD1 and AD2, into the FPGA.
In the FPGA, double-value method using the plastic to get two standard square wave, and then measured the time difference between two signals Δt, and the signal period T,
And calculate the phase difference (ΔΦ = Δt/T* 360 °). And into 1602 in the display. After testing, the measured phase error is less than 1 .
