奈奎斯特频率 meaning in English
nyquist frequency
turnover frequency
turnoverfrequency
Examples
- A solution is to use a low - pass filter to eliminate frequencies higher than the nyquist rate
解决办法是用低通滤波器滤除高于奈奎斯特频率的成分。 - Under the condition of one pixel image motion , adopting the modulation method , the ratios of the mtf with image motion to the idea mtf are 0 . 591 . the difference amount of mtf is shown . they are analyzed that the types of optic system , obstructive ratio influence the mtf and the methods improvement the imaging resolution of remote sensing camera
在存在一个像元的像移量时在奈奎斯特频率处，卷积法的有像移的mtf值和理想的mtf值之比为0 . 591 ，仿真法在存在一个像元的像移量时，有像移的mtf值和理想的mtf值之比为0 . 667 ，从中看到了两者之间定量的差异。
