Physical Model Formulations

Reminder of the various kinds of physical model representations we are considering:

• Ordinary Differential Equations (ODE)
• Partial Differential Equations (PDE)
• Difference Equations (DE)
• Finite Difference Schemes (FDS)
• (Physical) State Space Models
• Transfer Functions (between physical signals)
• Modal Representations (Parallel Second-Order Filters)
• Equivalent Circuits
• Impedance Networks
• Wave Digital Filters (WDF)
• Digital Waveguide (DW) Networks

We are mainly concerned with real-time computational physical models
