1.所谓轨对轨(rail-to-rail)运算放大器轨对轨放大器,指的是放大器输入和输出电压摆幅非常接近或几乎等于电源电压值。2.不是所有的rail to rail 运放输入和输出都接近电源,有的只是输入有的只是输出,当然也有的输入输出都是rail to rail 的,该类运放的最大特点就是可以扩展信...
1 著名的Nyquist采样定理尽管大家都知道,但还是提一提。大牛奥本海姆的《信号与系统》中是这样描述的:Let x(t) be a band-limited signal with X(jw) = 0 for |w|> wM. Then x(t) is uniquely determined by its samples x(nT),n=1,±1,±2,...,i...
