摘　　要：信号的细分与辨向电路是一种应用非常广泛的精密电路。该文的实验通过用分立元件代替集成五细分芯片,从而降低了实验成本。同时,为使实验结果直观,易于观察,实验中用信号发生器产生的正弦信号,再通过移相器产生余弦信号模拟光栅输出的两路信号,使实验现象更明显。The circuit for signal subdivision and direction discrimination is one widely used precise circuit. Instead of the integrated chips for five - subdivisions, the discrete elements are used in the experiment to reduce the cost. Meanwhile, in order to make the results more visible and easier to observe, the signal generator is used to produce a sinusoidal signal, which is then changed into a cosine signal through the phase shifter, and both signals simulate the output signals of the raster.
