Due to which of the following reasons excessive band width in control systems should be avoided?
A. It leads to slow speed of response
B. It leads to low relative stability
C. Noise is proportional to bandwidth
D. Presence of feedback
Answer:C
Due to which of the following reasons excessive band width in control systems should be avoided?
A. It leads to slow speed of response B. It leads to low relative stability C. Noise is proportional to bandwidth D. Presence of feedback
Explanation: Excessive Bandwidth causes increases in the noise with the same proportion as the bandwidth and hence noise is not good for any signal therefore the excessive bandwidth is not desirable.
