Advanced CATV System Concepts (1966)
By Bill Rheinfelder, Anaconda Astrodata
Recently new concepts for CATV Systems have been developed which together with a complete line of integrated equipment result in greatly improved performance quality and previously unheard of freedom from maintenance in CATV systems. In explaining these new concepts it is advantageous to go back to the basic standard, which is the real criterion of system performance, and that is the signal to noise ratio at the subscriber's TV set. According to SMPTE and other standards 40 db signal to noise ratio defines a flawless, studio-type picture of the highest quality. All efforts in CATV system design are therefore directed toward maintaining a minimum signal to noise ratio of 40 db to the subscriber's home.
