Abstract :
In recent years the growing use of vertical interval data transmission systems in television broadcasting, such as the Captioning for the Deaf system1 developed by the Public Broadcasting Service (PBS)*, has created a renewed interest in the problems of multipath distortion.2 This interest is heightened by the fact that new devices, such as microcomputers and charge coupled delay devices (CCD´s), make possible an economic solution to this problem for the first time, not only for data but for video as well3, although the work described herein has concentrated primarily on data applications.
