敘述
The 11759D dynamic ghost simulator easily simulates the ghosting and airplane flutter that commonly degrade terrestrial TV broadcasts. With the 11759D, ghost canceller or digital HDTV designs can be tested under the real-world conditions of multiple reflections and motion. The simulation of motion is required to account for the effects of tower sway, airplane flutter, and the movement of people, vehicles, and trees. The 11759D is ideally suited to simulate these phenomena.
