在没有外界反馈电路时所测出的电压放大倍数。Auo越高, 所构成的运算电路越稳定,运算精度也越高。Auo一般约为 104 107。-in the absence of external feedback circuit by measuring the voltage amplification. Auo higher posed by computing circuit, the more stable operating precision higher. Auo normall

系统，他主要完成对某设备上交流电源、直流电源、模拟电压、开关信号、脉冲信号等各种信号的采集工作。完成对上述信号的如下特征-system, he completed a pair of AC power equipment, DC power supply, analog voltage, switching signals pulse various signals in the collection. This signals the completion of the following c

模拟量节点模拟显示程序。比如汽车仪表盘，电压，油压量的显示

要用PIC单片机做模拟系统控制程序。电压，电流采集测量烦得很，这个电子八段管仿真程序就算是提前作个准备吧-Use the PIC microcontroller to do simulation system control program. Voltage and current measurements collected very annoying, this e-Ba Duan tube simulation program even if it is to prepare in adv
