98年電子技師:
以下連結為考選部考畢試題:
http://wwwc.moex.gov.tw/ExamQuesFiles/Question/098/035012300.pdf
第五題:
(一)Pr=Pt+Gt-自由路徑損耗+Gr
=20+17-195.6+39
=-119.6 (dB)
(二)Pr=Eb x Tb=Eb(dB)+Tb(dB)
-119.6=-193.9+Tb
Tb=74.3(dB)
Rb=-74.3(dB)
滿懷疑我的答案的,因為這樣算起來位元傳輸率很低,以實務來說很不正常吧?
請替我檢驗是否哪裡出錯了,謝謝。

第二題:

Lbar=2x0.3+2x0.2+3x0.1+3x0.15+2x0.25
接著我就不知道題目的意思了@@"
謝謝。
