An explanation of the whole comment would be great. I tried to look up Fourier transform on Wikipedia but it was a lot of math.
In: Mathematics
The Fourier transform converts horizontal information to perpendicular information by extracting many waveforms of different wavelengths. For example, if the horizontal information is an image, the Fourier transform can describe the amount of each color the image contains: more red than green.
