Effects Of Nonuniform Coaxial Cable On CATV Signal Quality (1970)

By W. L. Roberts and F. N. Wilkenloh, Continental Telephone Laboratories

Presented in this paper are results of observations of a monochrome television picture transmitted over coaxial cables disturbed by impedance periodicities. Systematic impedance variations were introduced at controlled levels during the cable manufacturing process. The resonance frequency of the periodicity selected was approximately 83 MHz, a convenient frequency for use with the selected test apparatus. 11 Equivalent 11 echo ratings were assigned to the various observed conditions. Similar comparisons were made on signals transmitted through resonant networks. Application of results to CATV system requirements is discussed.
