The sampling theorem shows that aliasing can be avoided if the Nyquist frequency is greater than the bandwidth, or maximum component frequency, of the signal being sampled.
采样定理表明，如果奈奎斯特频率大于样本的带宽或样本成分的最高频率，系统的采样失真可以避免。
So that ensure the camera on fly with satellite to obtain the demand ground pixel resolution over the Nyquist frequency. The paper also introduces the main parameters of foreign TDICCD camera.
确保相机装在卫星上飞行时，达到截止频率对应的地面像元分辨率，并介绍了国外TDIC CD相机的主要参数。
To adequately preserve the shape of your signal, you should sample at a much higher rate than the Nyquist frequency, generally at least 5 or 10 times the maximum frequency component of your signal.
为充分保证信号的波形不失真，你的采样频率应比Nyquist频率高出许多，通常是你信号最高频率的5到10倍。
