quantizing noise

The results of a rate of 3.2 bit/ pel and a weighted signal to quantizing noise ratio of 52.52 dB have been obtained by computer simulation.

计算机模拟结果，在压缩到3.2bit/pel码率时，在质量上达到加权信噪比为52.52dB。

In digitizing analogue signals, the digital signal is corrupted by the noise due to the inherent noise of the sampler and the quantizing noise.

在模拟信号数字化的过程中，由于采样器固有噪声和取样脉冲抖动以及量化噪声等因素的影响，取样量化后的数字信号被噪声污染。

It transfers the data source to dynamic Gauss White Noise. Then quantizing and optimizing the noise, we can get the final spread sequence.

它动态地把信源序列转化成高斯白噪声分布的数据流，再通过量化、平衡编码进行序列优化，以得到所需的扩频码。

The quantizing noise is an important factor which influences the quality of digital audio.

影响数字声频质量的主要因素之一是量化噪声。
