UPSTREAM BANDWIDTH CONDITIONING DEVICE
First Claim
1. An upstream bandwidth conditioning device that can be inserted into a signal transmission line of a CATV system in or proximate to a premise of a user, said device comprising:
- a tunable low pass filter;
a tunable high pass filter connected in series with the tunable low pass filter; and
at least one voltage control unit configured to adjust each of the tunable low pass filter and the tunable high pass filter between at least a first intermediate frequency range having a first width and a second intermediate frequency range having a second width, the first width differing in size from the second width.

Abstract
An upstream bandwidth conditioning device is provided that can be inserted into a signal transmission line of a CATV system on a premise of a user. The device includes a tunable low pass filter, a tunable high pass filter connected in series with the tunable low pass filter, and at least one voltage control unit. The voltage control unit is configured to adjust each of the tunable low pass filter and the tunable high pass filter between at least a first intermediate frequency range having a first width and a second intermediate frequency range having a second width. The first width differs in size from the second width.
