#103677 - Moving average window. Responding to: ???'s previous message |
The best method for removing such noise by averaging out is the moving average window method.
See: http://www.dspguide.com/ch15.htm Essentially, a new filtered reading is the average of the previous n readings. If I remember rightly, as a rule-of-thumb, n bits of noise requires a window size (ie. number of samples) of (2^(n-squared)). So, 2 bits of noise require n = (2^4) = 16. |
