An old Yamaha FM synthesizer is a fun way to play around with this concept, making familiar waveforms from sines either by playing a series of operators in unison at different frequencies, or more efficiently: modulating one operator with another at a certain frequency ratio.
I don't remember off the top of my head, but I think a it's a 1:2 ratio of carrier to modulator sine that mimics a square wave pretty well.
- khedoros1 10y agoA while ago when I was researching how the Yamaha OPL-series FM synths work, one program that I found was an instrument-builder. It gave you direct control over the hardware registers and showed some information about the waveforms that would be generated, if I'm remembering correctly. Dosbox has an OK OPL3 emulator built into it, so that's an easy, software-based stack to work from (ummm....if I could re-find the program that I was using).

- onirom 10y agoAdding sines is the basis of additive synthesis, you are correct about the ratio, i have made a visual additive synth which is just adding alot of sinewaves (Y axis represent frequencies) https://www.youtube.com/watch?v=jBg3DnElfHk https://www.youtube.com/watch?v=jBg3DnElfHk
