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。
The circuit can output analog voltage signals with positive and negative polarity according to the phase relation of encoder signals of orthogonal output type.
电力计量直接的对象是电子互感器,IEC标准统一规定了电子互感器的两种输出方式:数字瞬时值序列和模拟电压信号。
The direct object of power metering is electronic transformer. From IEC standards, electronic transformer has two kinds of output: digital signals and analog signals.
由于单片机所处理的信号是数字信号,对模拟电压信号进行检测处理时首先要用A/D 转换器件对其进行A/D转换,然后再进行处理。
Since the signal which is disposed by the SCM usually is the Digital Signals, before the Analog signals are checked by the processor, they must be conversed by the A/D converter.
