quantisation error造句

"' Noise shaping "'is a filtering process that shapes the spectral energy of quantisation error, typically to either de-emphasise frequencies to which the ear is most sensitive or separate the signal and noise bands completely.
If dither is used, its final spectrum depends on whether it is added inside or outside the feedback loop of the noise shaper : if inside, the dither is treated as part of the error signal and shaped along with actual quantisation error; if outside, the dither is treated as part of the original signal and linearises quantisation without being shaped itself.
It's difficult to find quantisation error in a sentence. 用quantisation error造句挺难的
