Due to which of the following reasons excessive bond width in control systems should be avoided ?
Correct answer: C. Noise is proportional to band width
- A. It leads to slow speed of response
- B. It leads to low relative stability
- C. Noise is proportional to band width
- D. None of the above
Explanation
A wider bandwidth allows more noise, because the total noise power generally increases with the frequency range passed by the system. Excessive bandwidth can therefore reduce signal quality, making noise proportional to bandwidth the intended reason.
