摘　　要：介绍一种具有极性判别功能的频率电压转换电路的原理.它可以根据正交输出型编码器信号的相位关系,输出具有正负极性的模拟电压信号.针对交直流速度伺服系统的光电编码器信号电压变换问题,给出了基于LM2907的F/V转换器的双极型频压转换电路.The principles of an F/V converting circuit with polarity judgment are introduced. The circuit can output analog voltage signals with positive and negative polarity according to the phase relation of encoder signals of orthogonal output type. In order to solve the problem of voltage converting of optical encoder signals in AC and DC speed servo system, the double polarity F/V converting circuit is given based on LM2907.
