Q. The magnitude spectrum of a continuous image is as given below.
a) Sketch the frequency response of the sampled spectrum if ωs =1.5 ωm along x and 3ωm along y directions in the figure below.
b) What is the minimum sampling rate along x and y to avoid aliasing ?
c) Do you believe this is the most efficient sampling scheme? Why or why not? If you were to select a more efficient sampling scheme in what ways would it make the sampling more complicated?
