Unformatted text preview: ..)? Ans: In the images reconstructed using frequencies satisfying the Nyquist criterion there seems to be an occurrence of phase shift such that the patterns in the reconstructed image seem to be offset compared to the patterns in the original image. 5. The reconstruction formula given by the sampling theorem requires an infinite number of samples, but in our implementation we are forced to use a finite number of samples: how is the reconstruction affected (pay attention to the quality of the reconstructed image near the boundaries. ..)? Ans: The effect of not having an infinite number of samples is that there is "blob formation" predominantly at the ends of the white bars at the boundaries of the image along with blurring. Also the reconstructed bars are not straight any more showing the induction of new frequency components....
