Introduction

As discussed in previous labs, there are three components to a physics-based guitar model: the excitation, the string and the body. The string model, as reviewed in Electric Guitar Lecture: Simple Strings, is based on the Digital Waveguide: a digital implementation of the solution to the Wave Equation. The body of the guitar is implemented as a filter, which can be measured by striking the bridge of your guitar with an impulse-force hammer. Lastly, we present simple methods for computing excitation signals to drive your string-model.
