What is the relationship between transmitted symbol rate and bandwidth?
Symbol rate and bandwidth are not related
Higher symbol rates require wider bandwidth✓الإجابة الصحيحة
Lower symbol rates require wider bandwidth
Bandwidth is half the symbol rate
الشرح
Each symbol change is a change in the transmitted waveform, and faster changes require more spectrum, so bandwidth grows roughly in proportion to symbol rate. It is proportional to the symbol rate, not half of it.
