And now would you switch it so we only hear the high end, a so-called high-pass filter.

现在切换到单独只有频，用是所谓滤波器。

The sturdy steel is generally used in 5G base station signal receivers, signal transmission filters and integrated circuit boards.

坚固钢一般用于 5G 基站信号接收器、信号发射滤波器和集成电路板。

And now would you switch it so we only hear the high end, a so-called high-pass filter?

现在会不会切换它让我们只听到端，一个所谓滤波器？

Now that's something that you could not explain unless that middle filter forces the photons to change their states.

现在，除非中间滤波器迫使光子改变它们状态，否则无法解释这一点。

Bose, for instance, does this by playing a welcome chime, and monitoring feedback from the internal microphone to customize noise-canceling filters, accordingly.

例如，Bose 过播放开机提示音，并监控来自内部麦克风反馈，从而相应地定制降噪滤波器来实现这一点。

Audio processing techniques like applying a low-pass filter to minimize salient events and adding reverb make sounds fade into the background.

音频处理技术（例如应用低滤波器以最大程度地减少突出事件和添加混响）使声音淡入背景。

And finally, four: Be aware of your personal perceptual filters. Elements of your experience, including your culture, community, and family, influence how you see the world.

最后，第四：个人感知滤波器，经验元素，包含文化、社区和家庭，影响着如何看待这个世界。

It won't reach those parts of the brain that do language acquisition. A block keeps it out. We call this block the effective filter.

它不会到达大脑中负责语言习得部分 一个街区把它挡在外面 我们称这个块为有效滤波器。

But if you had a filter oriented, say diagonally, well, then it would be convenient to describe things as a superposition of that diagonal direction and it's perpendicular anti-diagonal direction.

但是， 如果您有一个面向对角线方向滤波器，那么将事物描述为该对角线方向和垂直反对角线方向叠加会很方便。

So even though 0% of the photons passing through the first would pass through that last if nothing was in between, by introducing another filter, 25% of them now passed through all three.

因此，即使过第一个滤波器光子中有 0% 会过最后一个（如果中间没有任何东西），但过引入另一个滤波器， 现在有 25% 光子过了所有三个滤波器。

When  this impulse reaches the fault, it causes an electrical arc which can be heard as a thump above  the ground, usually aided by a handheld detector with a microphone and digital filters.

当这种脉冲到达故障时，会产生电弧， 可以听到地面上重击声，常由带有麦克风和数字滤波器手持探测器辅助。

(or at least with perfect filters it would be) Because all of the photons passing through that first one are polarized vertically, so they actually have a 0% chance of passing a filter oriented horizontally.

（或者至少对于完美滤波器来说是这样）因为穿过第一个滤波器所有光子都是垂直偏振，所以它们实际上有 0% 机会过水平方向滤波器。
