您要查找的是不是：
- It reduces the high-frequency quantization noise generated by imprecisely positioned object edges. 它滤除了由没有精确定位的物体边界信息产生的高频噪声。
- They have passbands which extend from DC, and the quantization noise is pushed up into the higher frequencies. 他们具有从直流延伸到截止频率的通带和被扩散到高频的量化噪声。
- Quantization noise analysis of linear phase frequency sampling FIR filters was discussed, and computation formula for measuring quantization noise was described in this paper. 主要分析了线性相位频率采样FIR滤波器中的量化噪声,并给出计算公式。
- There is a tradeoff, however, because lower resolution ADCs tend to have quantization noise which is correlated to the input signal, thereby producing larger frequency spurs. 这是一个权衡，因为分辨率低的ADC会产生与输入信号相关的量化噪声，从而产生高频激励。
- As the referenced frequency is fixed, the output frequency, the phase quantization noise and the resolution of frequency and phase are due to frequency word, the value of ROM and the bits of D/A converter, the bits of accumulator and ROM respectively. 时钟频率给定后,输出信号的频率取决于频率控制字,频率分辨率取决于累加器位数,相位分辨率取决于ROM的地址线位数,幅度量化噪声取决于ROM的数据位字长和D/A转换器位数。
