The TV transmission system should be as nearly transparent as possible. The continued improvement in color equipment has made it important that deficiencies in the transmission system be minimized. By observing the waveform distortion, phase and amplitude errors can be examined and relatively simple corrections can be applied. Time domain equalizers can enhance the corrections and cancel out antenna reflections and other anomalies in the system. These methods apply whether the distortion is within the range of the system or originate elsewhere. The picture portion can be improved greatly; much as stabilizing amplifiers reconstitute the pulse portion.
