Flatness of a transfer function
In terms of a transfer function, what conditions must be satisfied to ensure the output amplitude is maximally flat. Not a homework question. I'm just curious.86.8.201.210 (talk) 23:28, 4 May 2019 (UTC)
 * Our Butterworth filter article, particularly the maximal flatness section, might (or might not) give some clues.catslash (talk) 14:53, 5 May 2019 (UTC)
