If the input signal is already noisy ( as is usually the case ), the signal's noise may be larger than the quantization noise.
12.
The Redbook CD standard uses 16 bits, which keep the quantization noise 96 dB below maximum amplitude, far below a discernible level with almost any source material.
13.
:Dither can be used in audio mastering to randomize the quantization error, and some dither systems use Noise shaping to spectral shape of the quantization noise floor.
14.
Oversampling a signal results in equal quantization noise per unit of bandwidth at all frequencies and a dynamic range that improves with only the square root of the oversampling ratio.
15.
It occurs in transform-based MPEG-4 AAC, and Vorbis, and is due to quantization noise being spread over the entire transform-window of the codec.
16.
Some users experience a high level of background hiss and quantization noise when using the Walkman feature at low volume levels, a problem that first appeared in a firmware update.
17.
The SQNR reflects the relationship between the maximum nominal signal strength and the quantization error ( also known as quantization noise ) introduced in the analog-to-digital conversion.
18.
:" It reveals intriguing semidiscrete stochastic decision-making on the part of Drosophila . . . " . . . or, it reveals aliasing due to quantization noise.
19.
Assuming that the sampling frequency \ scriptstyle f _ s \, \ gg \, f _ 0, the quantization noise in the desired signal bandwidth can be approximated as:
20.
This demonstrates the noise shaping effect of the delta-sigma modulator : the quantization noise is " pushed " out of the low frequencies up into the high-frequency range.
