Problem I: Can someone help decribe what this circuit is meant to do ie. its basic operation? I am not quite sure what is going on. I have attached the input/output waves and the actual circuit diagram. The smaller signal (green) is the input (from the left) and the larger signal (yellow) is the output of the OPAMP. If you can just let out as much as your thoughst as possible because I might not be able to respond quickly. 13 hours time difference. Thank you in advance.
