Abstract

A method for compensating for multipath effects when receiving a vestigial sideband modulated TV signal, one portion of the spectrum of the undistorted TV signal being symmetrical with respect to a video carrier frequency, and deviations from the symmetry of the relevant portion of the spectrum that exists in the undistorted state being analyzed in order to suppress the multipath effects.
