Puh..so much to learn, so little time..

I wonder if I ever will be able to distinguish ringmodulation from amplitudemodulation, and more important - any reason to learn such details? Will it make me a better composer?

Yeah AM is just RM rectified.

Which means no negative values?

yup

the modulator signal will have no negatives, or no positives... the sound signal will have both.

If there is no negative values , and no positive, how will there be a signal at all? wouldnt the waveform just look like - compared to ~ (positive and neagive value)

no negative OR no positive, not both

the effect of all negative on the rectified signal is phase inverting the new modulated signal.

...to SEE what camsr is explaining in words try using an oscilloscope and use a triangle wave as mod

how will I benefit from distinguishing AM from RM?
