摘要
提出了一种基于MCU和程控放大器的数据采集与重构装置的设计与实现方法,该装置具有实时自动增益和动态模拟信号量程自动切换功能,能够解决因小信号难于分辨和大信号超过A/D转换器量程而造成的观测失真问题.
A way of designing the equipment with data sampling and reconstruction is presented, which is based on MCU and program control amplifier. This device has a function that can real time self-gain and automatically switch the measurement span of dynamic analog signal, and it can solve the problem of loss of true observation and measure, which is a result of weak - signal hard to recognize or large-signal exceeding the measurement range of A/D converter.
