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。

The Nyquist law is applied to all the conventional compression coding algorithms, which prescribes that the sampling rate must be at least as twice as the signal frequency.

在传统的压缩编码技术中，采样均遵循奈奎斯特定律，该定律规定采样速率要高于原信号频率的两倍。

The frequency aliasing due to sub-Nyquist sampling can be resolved by the proposed frequency aliasing resolving algorithm and information from the time-delay channel.

文中，欠采样所引入的频率模糊由增加的延迟通道提供的信息加以消除，并提出了相应的频率解模糊算法。
