Contrarily, if the frequency bandwidth of signal is finite, the time length of signal will be infinite when sampling in frequency domain, the time folding phenomenon will certainly happen.

反之，若信号的频带宽度有限，当进行频域抽样时，时域必然发生混叠。

Since there is an inherent trade-off between the amount of available bandwidth and the distance that a signal can travel, the more bandwidth is available, the farther a signal can travel.

既然在可用带宽数量与信号能够传播的距离之间存在固有的平衡，那么，可用带宽越多，信号就能够传播得更远。

By analyzing local properties of the signal, the application could, for instance, sharpen frames of video, or look for redundant information that can be removed to save memory or bandwidth.

通过分析信号的局部特性，应用程序就可以增强影像或者找出并删除多余的信息来节省内存或带宽。

The idea here is that IDT's switches will offload tasks that take up a lot of bandwidth from the digital signal processors, thus improving bandwidth performance by up to 20%.

The best part is, applying different levels of OAM twist to SAM-based transmissions theoretically allows an infinite number of streams per signal, meaning seriously increased bandwidth without the need for additional frequency.

And, because the digital signal occupies only 65% of the excess allotted bandwidth, stations can use the leftover spectrum to transmit text information like the artist's name, song title or more advertising.
