two-frequency Nyquist contour 双频Nyquist曲线
nyquist t frequency 奈奎斯特频率
Nyquist sampling frequency 奈奎斯特采样频率
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。
According to the Nyquist Theorem, the sampling rate must be more than twice the maximum frequency component of the signal being measured.
根据Nyquist定理，采样率必须是被测信号最高频率分量的两倍以上。
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。
