The following patterns below were created in scilab and their corresponding fft’s are shown beside them. We can observe the the annular circle and square produce a pattern which form only the shape is different i.e. they resemble the original … Continue reading →

Given that the circle I made of radius 0.1 out of a meshgrid of 128×128, I got a fast Fourier Transform given by figure below(on the left) and the shifted Fourier Transform shown beside it. Here after doing the shift, … Continue reading →
