1. The problem statement, all variables and given/known data Hi all, I hope you all can help me so I'm studying for my signals course and I encounter this example in the book, and the answer is there but the solution isn't..... The convolution integral exists for 3 intervals and I could evaluate the first two just fine..... however I can't find the limits of integration of the third. The third one corresponds to the fourth in the picture which is 2T < t < 3T The question and answer is shown in the picture attached Thank you!! 2. Relevant equations No relevant equations 3. The attempt at a solution I believe that the lower limit should be -2T + t, and the upper limit should be to T.
