Abstract :
An approach to the simulation of many of the channel impairments attributed to multipath fading and ghosting of a television signal is discussed. The use of the Hewlett Packard 11759D Dynamic Ghosting Simulator, which is capable of generating fading models ranging from static transmission conditions to dynamic cases of airplane flutter, tower sway, and reception by a mobile receiver in the simulation is described. All of these conditions can be used to subject future receivers, equalizers, and ghost cancellation circuitries to field-testing within the laboratory environment
