I don't know how an oscilloscope works... can someone tell me how the 4*5 1D sin/cos functions are related to the 2D image of the number 2?
It's obviously not the sum... I also don't think the 2 has been separated into small 2D chunks in which each one has some of the sins/cos?
I know harmonic analysis well but I'm not getting where the Fourier part is here
He describes how he calculated the coefficients by drawing the shapes on paper first.
