请看下面一段话“Understand Noise Sources: The three dominant sources of A/D noise are quantization, ac (phase noise, or jitter in sampling of ac signals), and wideband (white noise, digital feedthrough, etc.). The last one is the most amenable to dc histogram testing. Quantization noise is a large contributor to the signal's error power, but (in the absence of drift during the measurement) it does not cause multiple code "hits" to show up in a dc histogram. AC noise, resulting from aperture jitter, is also not a factor when the input signal is dc. The remaining source, wideband noise, is the major input-referred noise component measured by the histogram technique. ”
为什么在DC下面，量化噪声对DC测量的影响很小？
比如在重量，温度等的测试测量中我们主要精力在于减小White Noise，以提高无噪声编码分辨率～～～～～～～
