1976 Transmission of Analog Video and Digital Signals Over Analog-Repeatered Coaxial Lines
abstract
The transmission of digital telephony or data, alone and together with analog video, over analog-repeatered coaxial-cable lines is discussed. Expressions for the total random noise power and the signal-to-noise ratio (SNR) are derived. These expressions include the effects of thermal noise and the intermodulation distortion due to nonlinearity in the analog repeater amplifiers. The dependence of the SNR on system parameters, particularly the signal level and the repeater spacing, for systems that carry digital telephony, video, or both, is discussed and its implications on system design are noted.

1975 Intermodulation Noise and Products Due to Frequency-Dependent Nonlinearities in CATV Systems
abstract
The noise power spectral density and sinusoidal response at the output of analog coaxial cable lines having amplifiers with frequency-dependent nonlinear characteristics are derived. Their use for the design and optimization of coaxial cable systems for TV transmission is demonstrated. Tables are given from which the levels of the intermodulation products for conventional 12- and 30-channel video systems can be readily obtained.
