First claim
Opening claim text (preview).
We claim: 1. An amplifier for a cable network comprising: (a) said amplifier receiving a downstream analog input signal having a frequency spectrum from an input coaxial cable; (b) said amplifier converting said frequency spectrum of said downstream analog input signal to a downstream digital input signal, selectively modifying selected frequencies of said downstream digital input signal, converting said modified downstream digital input signal to a downstream analog output signal, and providing said downstream analog output signal to an output coaxial cable for a customer; (c) said amplifier receiving an upstream analog input signal having a frequency spectrum from said output coaxial cable; (d) said amplifier converting said frequency spectrum of said upstream analog input signal to an upstream digital input signal, selectively modifying selected frequencies of said upstream digital input signal, converting said modified upstream digital input signal to an upstream analog output signal, and providing said upstream analog output signal to said input coaxial cable; (e) wherein said amplifier is free from simultaneously providing said upstream analog output signal having a frequency range that is overlapping with said downstream analog output signal; (f) wherein the frequency range of said downstream analog output signal is adjustable by said amplifier; (g) wherein the frequency range of said upstream analog output signal is adjustable by said amplifier; (h) wherein said frequency range of said downstream analog output signal is overlapping with said frequency range of said upstream analog output signal; (i) wherein said downstream analog output signal and said upstream analog output signal do not provide a respective output signal at both the same time and at the same frequency; (j) wherein said amplifier attenuates signals in a guard band in (1) said overlapping frequency range and (2) one of said frequency range of said downstream analog output signal and said frequency range of said downstream analog output signal. 2. An amplifier for a cable network comprising: (a) said amplifier receiving a downstream analog input signal having a frequency spectrum from an input coaxial cable; (b) said amplifier converting said frequency spectrum of said downstream analog input signal to a downstream digital input signal, selectively modifying selected frequencies of said downstream digital input signal, converting said modified downstream digital input signal to a downstream analog output signal, and providing said downstream analog output signal to an output coaxial cable for a customer; (c) said amplifier receiving an upstream analog input signal having a frequency spectrum from said output coaxial cable; (d) said amplifier converting said frequency spectrum of said upstream analog input signal to an upstream digital input signal, selectively modifying selected frequencies of said upstream digital input signal, converting said modified upstream digital input signal to an upstream analog output signal, and providing said upstream analog output signal to said input coaxial cable; (e) wherein said amplifier is free from simultaneously providing said upstream analog output signal having a frequency range that is overlapping with said downstream analog output signal; (f) wherein the frequency range of said downstream analog output signal is adjustable by said amplifier; (g) wherein the frequency range of said upstream analog output signal is adjustable by said amplifier; (h) wherein said frequency range of said downstream analog output signal is overlapping with said frequency range of said upstream analog output signal; (i) wherein said downstream analog output signal and said upstream analog output signal do not provide a respective output signal at both the same time and at the same frequency; (j) wherein said amplifier attenuates signals in a guard band between a frequency of said downstream analog output signal and a frequency of said upstream analog output signal. 3. An amplifier for a cable network comprising: (a) said amplifier receiving a downstream analog input signal having a frequency spectrum from an input coaxial cable; (b) said amplifier converting said frequency spectrum of said downstream analog input signal to a downstream digital input signal, selectively modifying selected frequencies of said downstream digital input signal, converting said modified downstream digital input signal to a downstream analog output signal, and providing said downstream analog output signal to an output coaxial cable for a customer; (c) said amplifier receiving an upstream analog input signal having a frequency spectrum from said output coaxial cable; (d) said amplifier converting said frequency spectrum of said upstream analog input signal to an upstream digital input signal, selectively modifying selected frequencies of said upstream digital input signal, converting said modified upstream digital input signal to an upstream analog output signal, and providing said upstream analog output signal to said input coaxial cable; (e) wherein said amplifier is free from simultaneously providing said upstream analog output signal having a frequency range that is overlapping with said downstream analog output signal; (f) wherein the frequency range of said downstream analog output signal is adjustable by said amplifier; (g) wherein the frequency range of said upstream analog output signal is adjustable by said amplifier; (h) wherein said frequency range of said downstream analog output signal is overlapping with said frequency range of said upstream analog output signal; (i) wherein said downstream analog output signal and said upstream analog output signal do not provide a respective output signal at both the same time and at the same frequency; (j) wherein at least one of (1) a frequency band of said downstream analog input signal is shifted to a different frequency band of said downstream analog output signal, and (2) a frequency band of said upstream analog input signal is shifted to a different frequency band of said upstream analog output signal. 4. The amplifier of claim 3 further comprising providing a clock synchronization signal from said amplifier to another amplifier. 5. The amplifier of claim 3 further comprising providing a pilot tones from said amplifier to another amplifier. 6. An amplifier for a cable network comprising: (a) said amplifier receiving a downstream analog input signal having a frequency spectrum from an input coaxial cable; (b) said amplifier converting said frequency spectrum of said downstream analog input signal to a downstream digital input signal, selectively modifying selected frequencies of said downstream digital input signal, converting said modified downstream digital input signal to a downstream analog output signal, and providing said downstream analog output signal to an output coaxial cable for a customer; (c) said amplifier receiving an upstream analog input signal having a frequency spectrum from said output coaxial cable; (d) said amplifier converting said frequency spectrum of said upstream analog input signal to an upstream digital input signal, selectively modifying selected frequencies of said upstream digital input signal, converting said modified upstream digital input signal to an upstream analog output signal, and providing said upstream analog output signal to said input coaxial cable; (e) wherein said amplifier is free from simultaneously providing said upstream analog output signal having a frequency range that is overlapping with said downstream analog output signal; (f) wherein the frequency range of said downstream analog output signal is adjustable by said amplifier; (g) wherein the frequency range of said upstream analog
