ABSTRACT:
A television encoding system passes a modulated video carrier through a pair of SAW filters for attenuating and reversing the phase of the carrier during horizontal intervals. Another pair of SAW filters impart intermediate amplitude and phase changes to the video carrier during transitions into and out of the horizontal intervals to minimize switching transients and frequency disturbances in the color and audio carriers.
