H4-04 FOURIER ANALYSIS - DIGITAL OSCILLOSCOPE
- Additional Images:
- ID Code: H4-04
- Purpose: Demonstrates the Fourier spectrum of complex waves
- Description:
This experiment uses a digital oscilloscope with a fast Fourier transform module to determine the Fourier spectrum, simultaneously displaying the wave shape and the Fourier spectrum on its monitor. Any periodic wave from a wave generator or sound, such as a musical instrument or the singing voice, can be analyzed. A variety of waves can be input from wave generators, such as the standard wave shapes, and a microphone, such as steady-state instrumental or vocal sounds.
Invite student musicians to bring in their instruments for analysis.
