Pick two waveforms and watch how they combine. Convolution in time is multiplication in frequency, and multiplication in time is convolution in frequency.

Step view: f(τ) and h(t − τ)

  • 1Flip h(τ) to get h(−τ)
  • 2Shift it by t
  • 3Multiply by f(τ)
  • 4Area under the product = y(t)

Output y(t) = f(t) ∗ h(t)
