it''s a pretty simple concept but iirc it can be tricky to actually integrate

best explanation on the wiki page

"While the symbol t is used above, it need not represent the time domain. But in that context, the convolution formula can be described as a weighted average of the function f(τ) at the moment t where the weighting is given by g(−τ) simply shifted by amount t. As t changes, the weighting function emphasizes different parts of the input function."
