Hello, I'm Arado Ar 196. An edit that you recently made to Discrete cosine transform 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! Arado Ar 196 (C✙T) 11:35, 11 July 2022 (UTC)
