Signal types
There are many signal types that can be found:
- Sinusoids
- A few pure (or nearly pure) tones
- Harmonic
- Periodic waveforms (e.g. voice)
- Many (sometimes closely spaced) harmonics
- Shapred noise
- Signals that are (or are indistinguishable) from filtered (coloured) white noise
- Transients
- Whatever does't fit above I guess
