小中大【转载】:【求助】有关信噪比的定义
近红外中信噪比的定义从大体上讲很明确,但是具体到究竟怎么计算,我还是觉得有点糊涂。 有篇文献里是这么说的:Let's first define the spectral SNR as the root-mean-square(rms)value of the inverse of the 100% line: SNR=(1/100%line)rms ---(注:rms是下角标)---Eq(1)后面一段又说了:Following the definition in Eq.(1),we obtain the SNR values by taking the rms values......
