Summary Of Objectives

• Explain what physical models are and why they are useful.

• Review the behavior of traveling waves in a finite-length waveguide with inverting reflections.

• Provide intuition into how sampling works.

• Explain how to construct a digital waveguide vibrating string simulator.

• Demonstrate the operation of lowpass filters by example.

• Explore the behavior of a digital waveguide vibrating string simulator in pd by playing and adjusting the virtual string.

• Manually calculate parameters for the digital waveguide to reinforce understanding.
