推 stevegood:就是頻寬那麼大 中間可以有幾個頻道吧？ 07/19 19:03
推 guanrulee:(806-470)/6 他問你中間可以有幾個channel 07/19 22:49
→ guanrulee:一個channel有6MHz 從第十四頻道開始算 07/19 22:50
The UHF(Ultra High Frequency) television broadcast band begins with channel 14
and extends from 470MHz to 806MHz.If 6MHz is allocated for each channel,how
many channels can this band accommodate?
Ans.56;channels 14 to 69
答案有附在上面了
我的問題在於 我看不懂這題要幹麻
所以無從下手
煩請好心人士指點一下吧
謝謝
