Moving average

Question

• Generate a noisy sine-wave with the following parameters:
  duration = 0.5 s, amp = 3, freq = 0.5 Hz, sd noise = 0.15, where the noise is Gaussian
• Smooth the data with a moving average filter, with a
  filter-window of 15 points.
• Plot the noisy data, superposed by the smoothed curve.
