sampling lattice的意思|示意

However, when the signal is a circularly band-limited, the minimum sampling density for a hexagonal sampling lattice is 13.

当连续图像信号的频带处于一个圆形区域之内时，正六边形点阵结构的采样密度比矩形点阵结构的采样密度要降低13。

However, when the signal is a circularly band-limited, the minimum sampling density for a hexagonal sampling lattice is 13.4% less than that for a rectangular sampling lattice.
