Uncompressed Video and Audio: Sampling and Quantization - ScienceDirectdoi:10.1016/B978-0-240-81213-7.00002-2[Article in Czech]Ben WaggonerCompression for Great Video and Audio (Second Edition)
Transforming a continuous image into a digitized one is comprised of (at least) two steps: image sampling and image quantization. Both processes are described in this chapter, with a special emphasis on the former step. For simplicity, we will focus on the 2D case, the extension to 3D ...
See oversampling, quantization and PCM. Sampling Sound The faster the sampling rate and the larger the sample size, the more accurately sound can be digitized. An 8-bit sample breaks the sound wave into 255 increments compared with 65,535 for a 16-bit sample. Sampling Dialog This recording ...

Also, in Section 3.2 Oversampling using triangular dither, we generate the dithering signal by means of a timer configured in PWM mode, and some additional electronic components. If the application does not require the capture of signals smaller than th...
The ADC quantization noise is modulated to the higher frequency band during this process. The oversampled modulator output is then decimated through an ASRC and digital filter. The decimation removes the additional bandwidth caused by oversampling along with the shaped quantization. The result is a ...

measurement of each sample point on a numeric scale. Known as "quantizing," the sample point is turned into the closest whole number. The more granular the scale (the more increments), the more accurate the digital sample represents the original analog signal. Seeoversampling,quantizationandPCM....
The combined oversampling rate of the delta-sigma modu- lator and the internal 8X interpolation filter is 96fS for a 384fS system clock, and 64fS for a 256fS system clock. The theoretical quantization noise performance of the 5-level delta-sigma modulator is shown in Figure 11. 20 0 –...
