6^F推yudofu: 我根本看不懂問題，應該先修一下中文01/19 23:41

12^F推yudofu: 經過我一天的思考，我覺得他想要的是針對某個頻率的訊號的01/20 18:09

13^F→yudofu: trigger interruption線路01/20 18:09

2^F推yudofu: 他的問題在於評估轉換加輸出在2us內吧01/09 22:25

6^F推yudofu: 你會從問dsp開始問表示採樣手法這部分你已經有了，只是單01/10 11:23

7^F→yudofu: 純把資料打包，然後輸出(寫入)，以2u來說不算慢了，12MHz01/10 11:23

8^F→yudofu: 的8051大概才剛抽動兩下而已，應該不能很簡單地完成，如果01/10 11:23

9^F→yudofu: 要用通用CPU，最好還是先找一個你能找到的板子，先完成整01/10 11:23

10^F→yudofu: 個程序，然後把每一步驟都盡量分解，然後連續作多次看平均01/10 11:23

11^F→yudofu: (當然有神人是分解成單步執行看幾個clock)，然後看目前的01/10 11:23

12^F→yudofu: 平臺多快，再看瓶頸在哪裡，換一個平臺之後再重複這個動作01/10 11:23

13^F→yudofu: 。01/10 11:23

20^F推yudofu: latch吧01/10 17:22

5^F推yudofu: 電壓降是位能的損失，電阻可以當作損失的係數，因此可以當01/08 23:07

6^F→yudofu: 作是連續的變化，就好像吃下去的東西是先通過腸子才變成大01/08 23:08

7^F→yudofu: 便、還是先變成大便再通過腸子？當然是邊通過邊變成大便。01/08 23:08

8^F→yudofu: 你可以把R變成1/2R串聯1/2R、再無限分割下去就知道了。01/08 23:09

5^F推yudofu: 因為PCB考慮的是匹配，你用RLC的觀念去看的話難道你傳輸線01/02 14:26
