[MEC] 並聯阻抗化簡 How to simplify two impedances in parallel?

(允許非商業用途再利用的MediaTek晶片照片)

「分子通分,分母交叉相乘再相加。」這是最近復習到的阻抗簡化口訣,
剛好拿來練練畫圖。
When you have two impedances in parallel, and you want to simplify them, try this method. Especially when they are expressed in algebra.

1. Multiply the numerators to get the new numerator. 
2. Cross-multiply the numerators and denominators then add together to form the new denominator.


 

另外最近也發現如何提升從Visio輸出的JPEG檔案畫質,
只要將原本的Quality從75%提升到100%,
再把輸出的尺寸放大數倍就好了。

不過後來發現PNG才是無損壓縮,
輸出的圖像細緻度好像更好。
