What is the relationship between transmitted symbol rate and bandwidth?
- A.Symbol rate and bandwidth are not related
- B.Higher symbol rates require wider bandwidth (correct answer)
- C.Lower symbol rates require wider bandwidth
- D.Bandwidth is half the symbol rate
WhyHigher symbol rates require wider bandwidth. Sending symbols faster packs more transitions into the same amount of time, and representing those faster transitions cleanly in the frequency domain inherently requires more spectrum, so higher symbol rates require wider bandwidth, answer B. Symbol rate and bandwidth are directly related, not unrelated, lower symbol rates need less bandwidth rather than more, and bandwidth isn't simply defined as half the symbol rate, so A, C, and D are wrong.
