Abstract:
1. A forward amplifier signal equalization circuit for use with a forward amplifier for two-way coaxial cable systems having a distribution center distributing a plurality of forward signals, a plurality of coaxial cable lines extending therefrom, a plurality of tap ports connecting the plurality of forward signals from each coaxial cable line of the plurality of coaxial cable lines to respective terminals, and the two-way coaxial cable system having reception facilities for receiving a plurality of return signals from the two-way coaxial cable system, wherein the plurality of forward signals and the plurality of return signals passing along the two-way coaxial cable system in opposite directions are progressively attenuated in signal strength, the two-way coaxial cable system having a plurality of forward amplifiers at spaced intervals therealong, for receiving the plurality of forward signals passing along the plurality of coaxial cable lines, and amplifying the same, the equalization circuit comprising: a signal equalization circuit connectable in each forward amplifier of the plurality of forward amplifiers, said signal equalization circuit for equalizing the signal strengths of signals across a wave band of the plurality of forward signals and having a plurality of receptacles for receiving a plurality of plug in circuit components for varying the characteristics of the equalization circuit; and, a plurality of plug in attenuator components for said signal equalization circuit, said plurality of plug in attenuator components being adapted to interfit with said signal equalization circuit interchangeably, said plurality of plug in attenuator components having a range of varying performance characteristics, wherein each of said plurality of plug in attenuator components can be selected and plugged into said signal equalization circuit to produce performance specifications desired for each forward amplifier of the plurality of forward amplifiers at a predetermined location along the two-way coaxial cable system.
