    • It has the Intel 8286, so 10 megahertz.

      沒有,但我有成績單,保證讓你大吃一驚。

    • It has the Intel AD286, so 10 megahertz.

      它配備 Intel AD286,所以是 10 兆赫茲。

    • It's not to talk about MIPS and megahertz.

      不是去談論 MIPS 和 megahertz。

    • It's not to talk about nips and megahertz.

    22:22iPhone 徹底改變了 RF 濾波器! (The iPhone Forever Changed the RF Filter)
    • When we talk about RF filters, we are referring to those with a frequency band between 100 megahertz and 10 gigahertz.

      換句話說,就是裙擺的寬度,也就是頻寬。

    • But later, the SAW filter caught the industry's interest because it was a good, small analog filter that worked on frequencies from 10 megahertz to 1 gigahertz and beyond.

      所有的動作都在濾波器表面進行,這讓 SAW 濾波器更容易製造。

    35:19UPC 的聲波濾波器設計範例! (Design Example: UPC's Acoustic Wave Filter)
    • It's over 200 megahertz, which is something not very common in acoustic filters.

      所以你可以說,在採用階梯結構的聲波濾波器中,傳輸零點的數量應該等於諧振器的數量。

    • The blue one corresponds to 50 megahertz, the black one corresponds to 100 megahertz, and the red one corresponds to 200 megahertz, right?

      而且將傳輸零點放置在離諧振器中心頻率很遠的地方也很有用,沒有這些電感你就無法做到。

    14:55WiFi 7 實測:真的值得升級嗎?! (WiFi 7 tested: is it really worth the upgrade?)
    • Wi-Fi 7 has 320 megahertz channels in the 6 gigahertz band, whereas Wi-Fi 6 has 160 megahertz.

      還是更多的營銷手段,試圖迫使我們購買更多將來會很酷的東西?

    • It can reduce the EMI around 29 to 22 dB from low frequency, like the switching frequency, up to almost 50 megahertz.

      它可將低頻(如開關頻率)至近 50 兆赫茲的電磁干擾降低約 29 至 22 分貝。

    • we sweep the switching frequency from 200 kilohertz up to 1 megahertz.

      此外還有設備丟失。

      我們還在晶圓上使用較低頻率的 ICP,通常為 13 兆赫。

    • The next biggest barrier that I see is that people don't understand exactly how the 915 megahertz band, which Meshtastic uses, works.

      現在市面上有很多現成的裝置,這就成了最大的障礙。
