1F推: 1.用捲的比較簡單 2.非圓形相當客製化 3.沒有為什麼02/26 13:23
1F推: 自己買套件或者參加開源社團吧，現在硬體集成度太高了，單02/16 22:12
2F→: 打獨鬥搞不出甚麼的，都是進入公司實戰比較快，個人能做的02/16 22:13
3F→: 事情有限，很多硬體厲害的也是有公司的資源，不然現在用示02/16 22:13
4F→: 波器一堆設備又不像軟體可以要求學員自備。02/16 22:15
1F推: strength\default02/16 16:10
8F推: IC的運作就是不停地把電子從外面吸進來放上層變一、然後又02/15 23:47
9F→: 放到地上又變成零，於是不停地把位能都損耗掉，所謂驅動IC02/15 23:48
10F→: 也是一樣的02/15 23:49
12F推: 就算有超導IC頂多是沒有損耗而已，功還是要做的02/16 00:14
15F→: 你還是要作功訊號才會放大啊 ，就算把訊號加上位能，它傳02/16 22:16
16F→: 出去位能最後還是會不見啊02/16 22:16
4F推: 兩顆電池就能動的東西是能吃多大電流02/15 10:09
3F推: 你用切換開關的方式都是穩態而已，你要放AC source而且等02/04 02:05
4F→: 效電路也要換一下去google一下電容的等效電路就有了02/04 02:05
5F推: 而且loading應該要用動態的電流負載02/04 02:20
3F推: 除非兩個高電位的地不是參考到GND，否則當然是可以地，不02/01 09:10
4F→: 這種已經幾十年的做法有甚麼好懷疑的....02/01 09:11
1F推: 你把R分別設定成零跟無限大就知道會不會變了01/31 20:49
15F推: 只是個UART本來這樣就可以了 至於電阻你要變成戴維寧等效01/28 21:15
16F→: 電路，就知道為什麼是那個範圍了，很多人學了戴維寧跟諾頓01/28 21:15
17F→: 很會作化簡的題目，卻不曉得甚麼時候用...01/28 21:16
15F推: 奈奎斯是取樣別人的最低頻率，如果考慮到是輸出給人家，起01/26 23:54
16F→: 碼要20倍，只是才3.8mhz不考慮買震盪器或者用mcu的pll除頻01/26 23:54
17F→: 再轉弦波嗎？01/26 23:54
