         Implements a low pass filter with a moving average filter
 
         Parameters:
-        - alpha (float): attenuation coefficient, 0 < alpha < 1
-
-        - for a given dataset, the larger alpha is, the more closely the filtered function returned will match the function
-        - the smaller alpha is, the smoother the filtered function returned will be (but with a phase shift)
