Q. In control system excessive bandwidth is not employed because

  • (A) noise is proportional to bandwidth
  • (B) it leads to low relative stability
  • (C) it leads to slower time response
  • (D) noise is proportional to the square of the bandwidth
💬 Discuss
✅ Correct Answer: (A) noise is proportional to bandwidth
Explanation: in closed loop system the bandwidth of the system is more as compared to the open loop system and this is so required as higher the bandwidth means lower the selectivity and hence higher the noise.
