揭开一个公式(SNR 6.02N + 1.76dB)的神秘面纱（中文版）
This tutorial first derives the theoretical quantization noise of an N-bit analog-to-digital converter
(ADC). Once the rms quantization noise voltage is known, the theoretical signal-to-noise ratio
(SNR) is computed. The effects of oversampling on the SNR ...

[Bernard_Widrow,_István_Kollár]_Quantization 英文原著
Quantization or roundoff occurs whenever physical quantities are represented numerically. The time displayed by a digital watch, the temperature indicated by a digital
thermometer, the distances given on a map etc. are all examples of analog values
