In a second-order system, what does a damping ratio less than 1 indicate?

In a second-order system, what does a damping ratio less than 1 indicate?

Step 1: Understand what a second-order system is. It is a system that can be described by a second-order differential equation.
Step 2: Learn about the damping ratio. It is a number that describes how oscillations in a system decay after a disturbance.
Step 3: Know the values of the damping ratio. A damping ratio can be less than 1, equal to 1, or greater than 1.
Step 4: Focus on the case where the damping ratio is less than 1. This means the system is underdamped.
Step 5: Understand what underdamped means. It means the system will oscillate before settling down to its final value.
Step 6: Conclude that a damping ratio less than 1 indicates that the system will show oscillations in its response.
