A bar phantom is imaged by an LSI system, which is modeled as an ideal moving average system. The PSF of the system is

(a) If the bar separation of the bar phantom is what is the output of the image system?

(b) If the bar separation is what is the output of the imaging system?

(c) Derive the relation of the contrast of the output image with the bar separation and draw conclusion on the resolution of the imaging system.
