Convolution Calculator The Convolution Calculator computes the discrete convolution of two number sequences, as used in signal processing and polynomial multiplication. Enter both sequences separated by commas. — free online calculator.

Formula

(A ∗ B)[n] = Σ A[i]·B[n−i]
  • Convolution Calculator calculates its result from Sum Ai Conc, B N I. It uses the formula (A ∗ B)[n] = Σ A[i]·B[n−i]. Change any input to recalculate the result instantly.
  • The main inputs are Sum Ai Conc, B N I. Enter them in the units and format shown in the calculator.
  • Keep comparable quantities in compatible units whenever the formula combines or compares them.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Convolution

Inputs
  • Sum Ai Conc: 2
  • B N I: 11

Using Sum Ai Conc = 2, B N I = 11, the calculated result is 22.
