Abstract:

This laboratory assignment should teach the student about physical modeling and feedback control. These disciplines are applied to a digital waveguide model of a vibrating string. Students should complete the monochord laboratory assignment, the weighted monochord laboratory assignment, the harmonics laboratory assignment, the traveling waves laboratory assignment, and the digital waveguide model laboratory assignment first.
