11. Digital sampling introduces quantization error that manifests as low-level noise added to the reconstructed signal. 12. Audible quantization error is reduced by noise shaping the error according to an equal-loudness contour. 13. An ADC is defined by its perfect reconstruction is possible given an ideal ADC and neglecting quantization error . 14. Furthermore, while oversampling can reduce quantization error and non-linearity, it cannot eliminate these entirely. 15. The limited accuracy results in quantization error , a form of noise that is added to the recording. 16. Here, E ( z ) is the frequency-domain quantization error of the delta-sigma modulator. 17. Another problem is that color histograms have high sensitivity to noisy interference such as lighting intensity changes and quantization errors . 18. This introduces a quantization error but is normally accurate enough for most purposes if 10 or more classes are used. 19. What the ear hears as distortion is the additional content at discrete frequencies created by the regular and repeated quantization error . 20. An artificial jitter ( dither ) can be used in electronics for reducing quantization errors in A / D-Elements.
