摘要： A cable system, and a method for configuring a path of a cable system, wherein the group delay caused by one or more amplifiers having diplex filter networks is substantially equalized over all frequencies within a predetermined band by the use of one or more all-pass delay equalizers. A method of configuring a path includes steps of determining a delay versus frequency characteristic of the path within the predetermined frequency band, and providing from one to a plurality of all-pass delay equalizers in the path, wherein a collective delay versus frequency characteristic of the all-pass delay equalizer(s) within a predetermined frequency band is a mirror image of that caused by the amplifier(s), such that all frequencies within the predetermined frequency band are delayed by substantially the same amount and hence all frequency components of a signal arrive at a receiver at substantially the same time.

摘要： A downstream bandwidth output level tilt compensation device that can be inserted into a signal transmission line of a CATV system on a premise of a user. The device includes first and second filters to output first and second band signals, respectively. Detectors output a measurement representative of a characteristic (e.g., RF power) in the first and second band signals, respectively. A comparator uses the measurements from the detectors to determine a correction signal. A variable slope adjusting circuit is provided to adjust the gain slope of the downstream bandwidth responsive to the correction signal. The device includes a third filter after the variable slope adjusting circuit to pass a third band signals corresponding to the first and second signals. A second comparator uses measurements from the third signal to adjust the connection signal.
