What this calculator does
Discrete convolution works out convolves two finite number sequences to produce their discrete convolution sequence. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
Formulacₙ = Σₖ aₖ · b₍ₙ₋ₖ₎, summed over all valid indices k
