A. given the following equation for a general ac waveform, label v , ω, and φ. a = v cos (ωt + φ) b. start the waveforms 2015 software. you do not need the ad2 to be plugged in. using the demo discovery 2, simulate various waveforms using the wavegen tool. refer to appendix c for further details on how to use waveforms 2015. make a comment (1-2 sentences) on what happens to the waveform as you adjust the amplitude. make a comment (1-2 sentences) on what happens to the waveform as you adjust the frequency. make a comment (1-2 sentences) on what happens to the waveform as you adjust the phase shift. c. simulate three signals of varying amplitudes and phase shifts. maintain the frequency at 30 hz. d. express your three signals in both polar and rectangular form. e. plot the rectangular form of the equation on the complex plane.
