Hello. I need help with understanding one part of the convolution procedure. This doesn't involve any particular homework problem, but I'll use the following problem as an example:

I have 2 questions. If anybody can help me, I would greatly appreciate it.
1. When x(0-T) crosses the rectangle part of h(T), I understand the reasons for the integrals with the limits of t-1 to 0 and 1 to t-3. Can anyone confirm that the integral from 1 to 0 happens because x(0-T) is larger on the x plane than h(T)?
2. I don't remember how to obtain the inequalities of T for each respective integral (1 < t < 2, 2 < t < 3, etc. ) This eludes me. Please help. Thanks.
