5.19 An industrial plant manager has been promoted to a new position. His first responsibility is to characterize an image filtering system left by his predecessor. In reading the documentation, the manager discovers that his predecessor estab lished that the system is linear and position invari ant. Furthermore, he learns that experiments con- ducted under negligible-noise conditions resulted in an impulse response that could be expressed analytically in the frequency domain as H(u,v) elu/150 +/150] = +1 -e-l(u - 50)2/150+ (v - 50)/150] The manager is not a technical person, so he employs you as a consultant to determine what. if anything, he needs to do to complete the char acterization of the system. He also wants to know the function that the system performs. What (if anything) does the manager need to do to com plete the characterization of his system? What fil- tering function does the system perform?
