The conclusion is that only when the minimum sample rate is more than the double of the band of the signal, can the signal been resumed without distortion.

得出结论：只有抽样信号最低抽样率大于两倍信号带宽时，才能保证信号的无失真恢复。

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.

Thanks to Newt Gingrich and his band of zealous Republicans, the 1996 farm bill abolished the guaranteed minimum price, increased the quota for imports and, most importantly, scrapped the domestic cartel of producers.
