    • Siemens found that SAW filters were good, low-cost replacements for the old coil-and-capacitor-based filters in their TV sets.

      但後來,SAW 濾波器因為是一個很棒的小型類比濾波器,能在 10 MHz 到 1 GHz 甚至更高的頻率上運作,引起了業界的興趣。

    • Then in 1975, TV companies like Philips, Plessy and Siemens found that saw filters were good low cost replacements for the old coil and capacitor based filters in their TV sets.

      然後在 1975 年,像 Philips、Plessy 和 Siemens 這樣的電視公司發現,SAW 濾波器可以低成本地取代他們電視機裡舊的線圈和電容濾波器。

    • And that's a way RF current gets across a capacitor, where we build up a charge on one side of a capacitor, and the two plates of the capacitor, the charge on one side induces a charge on the other side, and we have basically an oscillating charge across the capacitor.

      這是射頻電流穿過電容器的一種方式,我們在電容器的一側積累電荷,電容器的兩塊極板上,一側的電荷誘導另一側的電荷,電容器上的電荷基本上是振盪的。

    • And that's the way RF current gets across a capacitor and there's where we—we build up a charge on one side of a capacitor, uh, and—and the other—on the two plates of the capacitor.

      是以,如果射頻電流密度越大,電壓也就越高。

    • So obviously, if you could make a capacitor that had anywhere near the energy density of a battery, and

      ELON MUSK:絕對是。

    • They had the energy density of a lead-acid battery, which for a capacitor, that's a big deal.

    • If you, for example, take an inductor and capacitor, or in this case, we have a transmission line of a certain length which has resonant modes that look like piano string resonant modes, this looks like a harmonic oscillator.

      我們來做一些數學運算。

    • And that just forms a capacitor in this X.
