System Response Experiments with a Simple, Portable Guitar String Platform.

This table-top experiment for education is suitable for courses in systems and signals, system dynamics, and vibrations. The experimental platform is low cost and portable so that students do experiments at their desks within a classroom setting and during a normal class period. The platform consists of a guitar string, guitar pickup, tuner, and a bridge. Students also need to have a signal processor unit, such as a National Instruments myDAQ, which turns a laptop into an oscilloscope and spectrum analyzer.
