Hello, I'm Uranium Site. An edit that you recently made to Pulse-amplitude modulation seemed to be a test and has been reverted. If you want to 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! Uranium Site (talk) 07:15, 20 October 2021 (UTC)
