摘要： A compensation device for maintaining a desired signal quality in transmitted signals includes a signal strength loss curve comparison component configured to compare a predetermined signal strength loss curve to a low band signal strength of a radio-frequency (RF) signal in an amplified forward path of a premise device. The compensation device also includes a gain curve adjustment component configured to output an adjusted gain curve across the RF signal in response to a comparison by the signal strength loss curve comparison component.

摘要： A frequency band selection device that can be inserted into a signal transmission line of a CATV system on the premise of a user includes at least two signal path sets between a tap side and a premise side. Each signal path set includes two discrete signal paths, a high frequency signal path for a downstream bandwidth and a low frequency signal path for an upstream bandwidth. The high frequency signal path and the low frequency signal path are separated by a cut-off transition frequency that is different for each signal path set. The device further includes a switch controller having at least two discrete switch positions. The switch controller chooses one of the switch positions as a result of an information signal. Each of the switch positions corresponds to a respective one of the signal path sets.
