Professor teaching us about convolution

[DmytriE]

I'm in class watching my professor teaching us about convolution. However, he keeps doing this by creating graphs and stuff. Is there a method through which I can solve convolution problems without having to draw the graphs?

A more general question is how do I treat unit step functions in a convolution problem?

Solve the equations, which is generally a point by point multiplication and summing process. I assume that is what the professor is doing, trying to illustrate the steps.

Or, use MATLAB :)

I don't understand your second question.
