3. Construct a time varying waveform y(t) by superimposing two sine waves with angular frequencies w₁ = 2π f₁ and w₂ = 2π f₂. Let fi 10 Hz and f = 30 Hz. = a) Add some non-trivial noise to the wavform and plot it over an interval of 1 second. b) Using you noisy data, determine the dominate frequencies f½ and fo using the standard technique we discussed in class. Your code should explicitly calculate these frequencies. You may make plots to help you but the code should calculate the numbers f½ and f2. c) Superimpose a waveform built from two sine waves using the determined frequencies from part b onto your noisy data in a single plot. I am not asking you to perform an explicit fit. (We are cheating a bit.)
