Both (A) and (B)<\/strong><\/p>\n<p>An open-loop system is a system that does not have any feedback. This means that the output of the system is not used to control the input. As a result, open-loop systems are more likely to oscillate than closed-loop systems.<\/p>\n<p>A closed-loop system is a system that has feedback. This means that the output of the system is used to control the input. As a result, closed-loop systems are less likely to oscillate than open-loop systems.<\/p>\n<p>However, both open-loop and closed-loop systems can oscillate if they are not properly designed. The following are some of the reasons why a system might oscillate:<\/p>\n<ul>\n<li>The system might have too much gain. Gain is a measure of how much the output of a system changes in response to a change in the input. If the gain is too high, the system will become unstable and oscillate.<\/li>\n<li>The system might have too much delay. Delay is the time it takes for the output of a system to respond to a change in the input. If the delay is too long, the system will become unstable and oscillate.<\/li>\n<li>The system might have a nonlinear response. A nonlinear response is a response that is not proportional to the input. Nonlinear responses can cause systems to oscillate.<\/li>\n<\/ul>\n<p>If you are designing a system, it is important to take steps to prevent it from oscillating. Some of the things you can do to prevent oscillation include:<\/p>\n<ul>\n<li>Using a feedback controller. A feedback controller is a device that uses the output of a system to control the input. Feedback controllers can help to stabilize systems and prevent them from oscillating.<\/li>\n<li>Using a low-pass filter. A low-pass filter is a filter that removes high-frequency components from a signal. High-frequency components can cause systems to oscillate.<\/li>\n<li>Using a phase compensator. A phase compensator is a device that changes the phase of a signal. Phase compensators can help to stabilize systems and prevent them from oscillating.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Open loop system&#8221; option2=&#8221;Closed loop system&#8221;
