The basic problems of CATV are really only two. First is obtaining a sufficient number of high quality TV signals and second is transmitting these signals through coaxial cable without degrading the original quality too much. The cable which is obtainable today does only one undesirable thing to the signal to any major degree. It attenuates the signal. It also causes a delay, but the delay, in general, is not a type which degrades the signal and the amount of delay is small. In a system of 1000 db, of cable attentuation the cable delay will be approximately 100 micro seconds.
