Q$6(10$pts$.)$:

This can be found in chapter five of the text which you can get a legal free pdf form the canvas course modules.

You can synthesize music $($singals$)$ several ways. One is the additive method where your sum pure sinusoids to build up a signal $($Fourier expansion$).$ Another method is the subtractive method where you create harmonics with square or saw$-$toothed wave and filter out the parts you do not want.

Plot at least $7$ non$-$zero terms of amplitude$/$phase line spectra of a saw$-$toothed wave form so that a sound engineer can evaluate which signals are available for manipulation.
