Generating Square Waves Using Harmonics (Geogebra)

This is a Geogebra program for use as a visual aid in teaching the concept of harmonics in the context of generating a square wave from sinusoidal waves. This program has been designed using Geogebra 5.0 (download version). The program will visually demonstrate how the addition of sine waves of specific amplitudes and frequencies can be added together to produce a periodic square wave signal. The specific amplitudes and frequencies on the harmonics are also displayed in a table.

This resource will visually engaged your students and give them an intuitive understanding of how a signal can be broken down into the various harmonic constituents.
