jitter dithering 区别？

jitter is the random noise on the clock signal. in the frequency domain, jitter is equivalent to the phase noise.
dither is the technique that adds white noise onto something, usually is quantizer, to make it more linear. dither sometimes is used in Sigma-Delta ADCs to remove the idle tones.

thanks.

对象不一样，不是表征一个东西的。

白噪声，加上之后呢?
