Day 17 RLC Circuit Response

This lab emphasized the modeling and testing of a second order circuit containing two resistors, a capacitor, and an inductor. The step response of the given circuit is analyzed and tested.

For our pre-lab, we were instructed to write the differential equation relating Vin and Vout, as well as estimate the damping ratio and natural frequency of the circuit. Below are those calculations:

Our constructed circuit is shown below. Two resistors, a capacitor, and an inductor. We use our oscilloscope to measure the voltage output across our second resistor.

As we can see from the measured signals, our circuit behaved as expected.

The objective of our lab was again achieved. We learned how to analyze circuits containing a resistor, capacitor and an inductor in parallel. Today we observed one of three responses: the over damped circuit.
