Special signals and spatial frequencies: Generate images of sinusoidal signals with spatial frequencies fx = 5c/ph, fy = 0c/ph, fx = 5c/ph, fy = 10c/ph, and fx = 1.5c/ph, fy = 2.5c/ph. Calculate the horizontal 5 and vertical periods of the signals. Determine the spatial frequency and period along the line y = 3 x of the signals. Generate versions of the signals with di?erent amplitude A and phase φ. Comment on the output images.
