File source and copyright licensing problem with File:Positive loop feedback.jpg
Thanks for uploading File:Positive loop feedback.jpg. However, it currently is missing information on its copyright status and its source. Wikipedia takes copyright very seriously.

If you did not create this work entirely yourself, you will need to specify the owner of the copyright. If you obtained it from a website, please add a link to the page from which it was taken, together with a brief restatement of the website's terms of use of its content. If the original copyright holder is a party unaffiliated with the website, that author should also be credited. You will also need to state under what licensing terms it was released. Please refer to the image use policy to learn what files you can or cannot upload on Wikipedia. The page on copyright tags may help you to find the correct tag to use for your file.

Please add this information by editing the image description page. If the necessary information is not added within the next days, the image will be deleted. If the file is already gone, you can still make a request for undeletion and ask for a chance to fix the problem.
