Hello, I'm Oshwah. Wikipedia is written by people who have a wide diversity of opinions, but we try hard to make sure articles have a neutral point of view. Your recent edit to Electronic filter topology seemed less than neutral to me, so I removed it for now. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you.  ~Oshwah~  (talk) (contribs)   04:58, 24 January 2019 (UTC)
