Grant discusses X-mod and noise in cable plant design.
Topics include temperature vs. cable loss, automatic temperature compensation, understanding AGC and AGC in system design. Economics of auto-regulation and potential AGC problems also covered. Defines some basic CATV terms, followed by a detailed explanation of the basic theories upon which systems are designed. Topics include wideband transmission, electromagnetic spectrum, coaxial cable transmission and spectrum allocation. This video deals in-depth with the related mathematics by covering ratios, decibels, logarithms, power ratios, the relationship between voltage and power calculations.
