Great post, I'm intrigued!
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
- crististm 7y agoIt's the sum of the sin/cos with coefficients. There are two outputs, one for X and one for Y that draw the shape of the number without "raising the pen". He describes how he calculated the coefficients by drawing the shapes on paper first.
- debbiedowner 7y agoAh okay he is plotting x(t) vs y(t) to make 2d images where x is a sum of sines and y is a sum of cosines. These are called Lissajous figures.
