以下為題目
一、(一)我們可以將數位的資料(digital data)
轉成類比的信號(analog signal),
以便可以在類比的通訊系統傳輸。
如果我們用的baud rate為1000,調變的方式是Binary FSK
(Frequency Shift Keying)的話,那data rate會是多少?
---
高點的網路上答案是把Binary FSK當成 1 bit 計算
data rate 是 1000 bps
高點103年網路講義答案是把Binary FSK當成 2 bit 計算
data rate 是 2000 bps
以講義上對FSK的說明,我覺得好像是 1 bit ,
可是實際上BFSK到底是 1 bit 還是 2 bits ??
祝大家金榜題名
