Convolution Calculator

Calculate discrete convolution of two sequences with step-by-step solutions. Free and instant.

Convolution Calculator

Compute discrete convolution (f * g)[n] = Σ f[k]·g[n−k] with step-by-step solutions.

Result (A * B)

[1, 3, 3, 1]

Step-by-step

  • n = 0: a[0]×b[0]=1 = 1
  • n = 1: a[0]×b[1]=1 + a[1]×b[0]=2 = 3
  • n = 2: a[1]×b[1]=2 + a[2]×b[0]=1 = 3
  • n = 3: a[2]×b[1]=1 = 1
