Fourier Transform Explorer, Year 12
Students build waveforms from harmonic components and see the time-domain signal and its frequency-domain spectrum side by side, adjusting amplitude and phase to watch both representations respond. The full interactive is available to licensed Education Universe users.
Year 12, UndergraduateExplorer
Learning outcomes
- Describe a periodic signal as a sum of harmonics.
- Relate the time-domain and frequency-domain views of a signal.
- Explain the effect of amplitude and phase on a waveform.
Teaching guidance
Ask students to predict the spectrum for a waveform before building it.
