Offered by Cleveland State University's Department of Electrical and Computer Engineering, these five virtual experiments "are intended to broaden and deepen a student's understanding of linear systems concepts by allowing interactive exploration of various issues." The experiments start by introducing a certain situation and giving necessary background to understand the properties of the particular linear or nonlinear system. Following the introduction, one or two Java applets allow the user to see the system's response over time. Some topics demonstrated in the experiments include superposition, state feedback, and others.
