Student assignment EE Digital and signals

I need my Signals & Systems assignment on convolution worked out by hand on a tablet or similar device, then exported as a single PDF. Every page should read like well-kept class notes: headings for each sub-problem, the core formulas up top, followed by every algebraic or integral step so the logic is easy to follow. Think of it as a hybrid between summary sheets and a full worked solution—both the key ideas and the detailed derivations must be there.

Please write in a neat, clearly legible print style. No fancy calligraphy is necessary; consistency and readability matter most. Once finished, combine all pages into one PDF and make sure it opens cleanly on any viewer.
