An introduction to the step response of a 2nd order system with complex poles and zero initial conditions using Laplace techniques. Includes illustrations on numerical examples.

Tutorial on the computation of responses for under damped 2nd order systems, using Laplace and time domain methods. Includes worked solutions.

Beginning from the standard form for 2nd order models using damping ratio and natural frequency, gives questions on simple and quick analytic computations can be used to produce an accurate sketch of the step response (for zero initial conditions).Includes worked solutions.
