Convolution and the Fourier Transform explained visually

Convolution and the Fourier Transform go hand in hand. The Fourier Transform uses convolution to convert a signal from the time domain into the frequency domain. In this video I demonstrate an intuitive way of understanding what convolution is, explain the convolution equation and demonstrate how it is used in the Fourier Transform. 0:00 - Introduction 0:17 - A visual example of convolution 0:52 - Ident 0:57 - Welcome 1:19 - The formal definition of convolution 2:24 - The signal being analyzed 2:36 - The test wave 3:00 - The independent variable 3:31 - Stage 1: Sliding the test wave over the signal 4:34 - Stage 2: Multiplying the signals by the test wave 4:51 - Stage 3: Integration (finding the area under the graph) 5:31 - Why convolution is used in the Fourier Transform 7:28 - Challenge Other works used in this video: 2 Crowd Green Screen and Crowd Talking Sounds by Creative Film    • 2 Crowd Green Screen and Crowd Talkin...
