Abstract :
Multipath interference causes a TV ghost image that is either an attenuated, shifted version of the original image, or an attenuated, shifted Hilbert transform of the original, or a bit of both. This complete model for the ghost image will be proven by modeling the vestigal sideband TV signal as a single sideband signal, after which the multi-path signal will be demodulated
