1、 由于后级采样电子电路将正弦波整形为方波，因此模拟电路可直接输出频率可调的方波给后级。
2、 三相交流发动机由于发电绕组是120度对称安装，其输出的三相波形为相隔120度的三相正旋波，因此模拟电路必须输出三相相序对应的方波。
3、 三相交流发动机发出的三相交流电压相序隐含着电机的旋转方向，因此输出方波的相序应可调，以适应电机旋转方向的变化。
4、 后级采样电路为脉冲计数方式，为确保计数的准确性，模拟电路应输出占空比为50％的标准方波。
-1, after the class as a result of sampling shaping electronic circuit for the square wave to sine wave, so analog circuits can be directly adjustable output frequency square wave to the after-class. 2, three-phase AC motor windings as a result of power generation is 120 degrees symmetrical installation, the output waveform for the three-phase three-phase 120 degrees apart are chiral, so analog circuits must be three-phase output phase sequence corresponding square. 3, three-phase AC motors issued three-phase AC voltage phase sequence implied a motor rotation direction, so the output square wave of phase sequence should be adjustable to adapt to changes in the direction of motor rotation. 4, after the level sampling circuit for the pulse counting mode, in order to ensure the accuracy of counting, analog circuits should output 50 duty cycle for the standard square wave.
