不好意思 小弟這有幾題想請教各位
100年國營電路學
http://info.taipower.com.tw/TaipowerWeb//upload/files/27/1000424_Q1517A.pdf
1.第九題 答案(A)
在 A 跟 B 之間選 要如何判斷是 A 而不是B呢?
2.45、46題 答案(B) (B)
這題想法是 令 外加電壓VX 流入IX
(2-j4)端電壓=V1 ,Io=V1/(2-j4)
I1=(VX-V1)/(4+j3)
整理出 VX= 口*IX + ??
但是算了好多遍還是算錯,請問有各好辦法求得嗎?
3.49題 答案(D)
電路基礎太差,又Google不到= =
這題真的不會,麻煩大大幫忙
4.55題 答案(C)
沒看過這樣題目,不知從何下手..
5.59、60題 答案 (C) (D)
題目正相史密斯 Vcc=15
算 V+ = +7.5V
V- = -7.5V 輸入 +5V -5V
但照輸入輸出曲線 似乎沒辦法判斷是 15V 還 -15V
也是到這就卡住了
以上這幾題麻煩各位大大幫忙,謝謝!!
