Cascaded RC Circuit in Simulink and Simscape

This example shows two models of a cascaded RC circuit, one using Simulink® input/output blocks and one using Simscape™ physical networks.

The Simulink model is built using signal connections, which define how data flows from one block to another. The Simscape model is built using physical connections, which permit a bidirectional flow of energy between components. Physical connections make it possible to add further stages to the RC circuit simply by using copy and paste. Input/output connections require rederiving and reimplementing the circuit equations.

The circuit is driven by a voltage square wave. Resistance and capacitance values are defined using MATLAB® variables.
