## Homework Statement:

- From the oscilloscope reading, find the undamped frequency of oscillation, damped exponent, and damped frequency of oscillation if the damping ratio is .1.

## Relevant Equations:

- shown below

I know the following equations for if the damping ratio is less than 1: $$\sigma = -\zeta \omega_n$$ $$\omega = \sqrt{(1 - \zeta ^2)\omega^2_n}$$ |

Measuring the voltage between node 2 and ground (blue), and the voltage Vc4(t) (green) I get the following reading:

what is the undamped frequency of oscillation, damped exponent, and damped frequency of oscillation? All I really need is the undamped natural frequency because I will be able to use the formulas to find the rest. How can I find it? Is it just the frequency of the green signal? Vc4(t)?
