Question: 11 -

In which of the following systems can multiple signals be used?

Options:

  1. None

  2. Non-Feedback

  3. Feedback

  4. Feedforward

    5. Answer:

    Feedback
    Solution not available.

Question: 12 -

What should be the nature of bandwidth for a good control system?

Options:

  1. Small

  2. Medium

  3. Large

  4. All of the above

    5. Answer:

    Large
    Solution:

     Bandwidth is defined as the difference in the highest frequency and lowest frequency and bandwidth must be large for the good control system and for higher bandwidth noise is also large.

Question: 13 -

Sampling is necessary ____________

Options:

  1. Automated control system

  2.  Where high accuracy is required

  3. Non automated control system

  4. In complex control system

    5. Answer:

     Where high accuracy is required
    Solution:

    Sampling is the process where the continuous systems are converted into discrete time systems with the help of zero order hold of the signal and sampling is necessary where high accuracy is needed.

Question: 14 -

Identify one of the possible effects of a control system with excessive noise.

Options:

  1. Saturation in Amplifying Stages

  2. Loss of Gain

  3. Vibrations

  4. Oscillations

    5. Answer:

    Saturation in Amplifying Stages
    Solution not available.

Question: 15 -

 Feedback control system is basically ______________

Options:

  1. Low pass filter

  2. Band pass filter

  3.  Band stop filter

  4. High pass filter

    5. Answer:

    Low pass filter
    Solution:

    Low pass filter is mainly as integral controller and it is used as the controller in the system so as to increase the accuracy by reducing or proper eliminating the steady state error of the control system.
