As is the case with most random noise sources, you obviously want to whiten the output before adding it to your entropy pool.
Actually, you want to whiten it before output, not before input. Whitening before input is a problem, because you can't run an estimator on the input -- because it's been whitened. If you want to know the unbiased entropy of a source, you want the raw inputs. If you don't care about the unbiased entropy, then you don't. Jon
