How to set the additional filtering? Input a figure 1, 2, 3…?

The LOW NOISE setting applies additional filtering (typically a factor of two) to the signal
按字面意思,当使用LOW NOISE设定时,会对信号产生额外过滤,一般是两倍
通常对于过滤降噪,是以倍数计,a factor of two 是2X(或x2), 原有过滤x2,其实是增加了一倍過濾,噪声相对地减少了一半(1/2)

有点印像了。 In signal filtering, it seems that +/- 5dB (or 10dB ???) would increase or reduce the signal by 2 times ???
