Increasing The Channel Capacity Of Single Ended CATV Amplifiers (1975)
By E. W. Finlay, York Cablevision Limited and J. Cappon, J. Cappon & Associates Limited
Investigations were conducted on an operating cable television system to explore methods of increasing the channel capacity of broadband single-ended amplifiers.
The resulting data indicated that this could be achieved by judicious selection of the carrier frequencies.
An original method of deriving the desired carrier frequencies is presented to enable channels to be added in the midband spectrum 120-174MHz. The equipment requirements are discussed, and test results obtained under dynamic conditions allows a comparison with standard carrier operation.
