Digital Signal Processing: by Steven Smith is free on the web and has an excellent example of solving convolutions graphically.

The joy of convolution is a website that shows you what convolution looks like graphically.
Its at jhu.edu/signals/convolve/index.html

Also Steven Smith's book is a brilliant book (not only for convolution) and I also highly recommend it :D
