First set of 8 samples: 0111 1111 1000 0000 0111 1111 1000 0000 0111 1111 1000 0000 0111 1111 1000 0000 ------------ 11 1111 1100 Divide by 8: 0111 1111 Second set of 8 samples: 0111 1111 1000 0000 0111 1111 1000 0000 0111 1111 1000 0000 0111 1111 1000 0000 ------------ 11 1111 1100 Divide by 8: 0111 1111 The LSB does not flicker anymore. This is only a specific case where it changes on every sample, but how often is this the case? What if it changes every 8 samples? Does the flickering go away then? I would also go with the hystersis + moving average method suggested by Kai, it is the standard method I use on any sampling I do. |
