例句

  1. Tests indicate that the square-law detect dynamic range is increased up to 30 dB and the errors of nonlinearity is less than ± 0.02 dB after calibrating.
  2. 实验表明修正后检波器的平方律检波动态范围扩展至30dB，非线性误差小于±0.02dB。
  3. In this method, firstly the histogram is divided into four sub-layers equally, and then according to the probability density distribution, we will re-map gray value range of sub-layers to complete the expansion of the dynamic range, thereby increased the contrast of the image.
  4. 该算法首先将图像的直方图平均分割成四个子层，然后根据每个子层内灰度值累积概率密度和的大小，将子层的灰度值范围重新映射，从而提高图像的对比度。
  5. The conversion precision of the analog signals and the dynamic range of the AGC are increased by the over sample and digital filter technologies, and the convergence rate of the AGC is speeded up by variable step.
  6. 采用过采样和数字滤波技术，增加了模拟信号的转换位数，增大了AGC的动态范围；采用可变步长设计加快了AGC的收敛速度。
