Parallel RLC Circuit Response Overview:         This lab will emphasize modeling and testing of a parallel second order circuit containing two resistors, a capacitor, and an inductor. In this assignment, the step response of the given circuit is analyzed and tested. The measured response of the circuit is compared with expectations based on the damping ratio and natural frequency of the circuit. We clearly see the period and frequency through the graph this time and the frequency is around 1k Hz

Series RLC Circuit Step Response (continue) Part2 Overview: consists of a simple design problem: the circuit of Part I is to be re-designed to make it critically damped, without changing either the natural frequency or the DC gain. Again, the circuit step response is measured and compared to expectations. Still the same problem, that we cannot see any damping from the graph due to the low sensitivity.

Series RLC Circuit Step Response Part1 Overview: the step response of a given circuit is analyzed and tested. The measured response of the circuit is compared with expectations based on the damping ratio and natural frequency of the circuit. Conclusion Since the response frequency is too high, the equipment cannot measure the frequency correctly.
