✦ Synopsis
A new simple method of obtaining the multipath channel distortion within a terrestrial transmitted video signal is presented. The method finds in isolation the VSB-filter-induced relative detected quadrature ghost amplitudes, which had previously been difficult. The method is based upon correlation of the received signal with a version of the PAL GCR standard signal which has been modified by the inherent quadrature forming filter spectrum of the receiver VSB filter. Results are presented from simulation and a hardware prototype solution.
