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

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
