The key ”trick” of the operation seems to be this revelation:
> In other words, performing the convolution of two signals in time domain is equivalent to multiplying them in the frequency domain.
Great article, as it breaks down a complex idea into much smaller steps that even my math challenged mind can somehow grasp, but did I miss a step? Or is it left as an exercise to the reader to look up? I was already stretching my math ability to that point, but it felt a little bit like - “and then, draw the rest of the F-ing owl” to me. Is it just me?
