You would need hundreds of different frequencies at the same time to approach random "white" noise. And, as Solderman said, filtering out all but one tone would be a nightmare.
Sine wave = no harmonics
Saw wave = all EVEN harmonics - each in inverse level (volume) to it's number (higher=softer)
Square wave = only ODD harmonics
Most basic useable synth= (think Korg Monotron)
Oscillator - Low-pass filter - VCA - LFO - EG
Next step up= (think Roland Gaia)
Two VCOs, VCF with LP, BP settings VCA, 2 LFOs, 2 EGs, basic effects.
Again - we may not be seeing eye-to-eye here;
Do you mean what nember of filters would a synth need to cover most of the "popular synth sounds you hear"?
If so, then my answer (FWIW) is two: A low-pass/band-pass VCF and a high-pass adjustable.
