在生产和科研中,往往需要对多个不同的物理量进行同步测量,这就要求测量仪器必须具有同步采集数据的功能。采用CMOS电路的电子测量仪器常用如图1所示的电路实现这种功能。
In production and scientific research, often need to measure a plurality of different physical quantities synchronously, this requires the measuring instrument must have the function of gathering the data synchronously. Electronic measuring instruments using CMOS circuits commonly used circuit shown in Figure 1 to achieve this function.
