Question

Q6 (10pts.): 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. V(signal) 1.0V 0.9V 0.8V 0.7V 0.6V 0.5V 0.4V 0.3V 0.2V 0.1V 0.0V 1.0ms 1.2ms 1.4ms 1.6ms 1.8ms 2.0ms 0.0ms 0.2ms 0.4ms 0.6ms 0.8ms
