SMOOTH SIGNAL (Average Filter)
========================================
PURPOSE:
  Reduces noise by averaging values.
LOGIC:
  Each output = average of all previous values
EXAMPLE:
  Input: [10, 20, 30]
  Output: [10, 15, 20]
USER ACTION:
  No mandatory changes required.
  Optional: Modify averaging logic inside loop if needed.
