Hello, I'm Graham87. An edit that you recently made to Pulse-density modulation seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! Graham 87 15:06, 6 April 2017 (UTC)
