Hello, I'm Septrillion. I noticed that you recently removed content from Digital signal processing without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.

If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the help desk. Thanks. creffett (talk) 22:53, 22 April 2019 (UTC)

Please stop adding unsourced content, as you did on MIT BBS. This violates Wikipedia's policy on verifiability. If you continue to do so, you may be blocked from editing Wikipedia. Home Lander (talk) 00:24, 26 April 2019 (UTC)
