Feedback can always reduce the effects of noise and disturbance on system performance?

Correct Answer: True
Feedback has many advantages as it can reduces the effects of noise and disturbance on system performance by increasing speed of response.

Consider the following statements with respect to the feedback of the control systems. i. Feedback can improve stability or be harmful to stability if it is not properly applied. ii. Feedback can always improve stability iii. In many situations the feedback can reduce the effect of noise and disturbance on system performance. iv. In general the sensitivity of the system gain of a feedback system of a parameter variation depends on where the parameter is located.

In general the sensitivity of the system gain of a feedback system of a parameter variation depends on where the parameter is located.

Consider the following statements: 1. The effect of feedback is to reduce the system error 2. Feedback increases the gain of the system in one frequency range but decreases in another 3. Feedback can cause a system that is originally stable to become unstable Which of these statements are correct.

In the following passage, some of the words have been left out. Read the passage carefully and select the correct answer for the given blank out of the fouralternatives.
Job performance is ______ by a number of factors. Motivation alone does not lead to increased performance. Ability and technology moderates the relationship
between motivation and performance. The higher the levels of ability and motivation the ______ the level of performance will be. However, increasing motivation
beyond an ______ level tends to ______ a dysfunctional result because it is ______ by an increased level of anxiety.
