Abstract:
1. A downstream bandwidth conditioning device that can be inserted into a transmission line of a CATV system on or proximate to a premise of a user, the device comprising: a supplier side connector; a user side connector; a forward path extending at least a portion of a distance between the supplier side connector and the user side connector; a coupler connected within the forward path, the coupler providing a secondary path; a tuner being connected to the coupler and being tunable based on an input from a microprocessor, the tuner providing a tuner output of a selected channel, the selected channel being at least one of a high frequency channel and a low frequency channel; a channel analyzer being connected to an output of the tuner, the channel analyzer providing the microprocessor with a modulation output, the modulation output differing when the selected channel is an analog modulation versus when the selected channel is a digital modulation; a slope adjustment circuit being connected within the forward path between the coupler and the supplier side connector, the slope adjustment device being adjustable based on an slope control output provided by the microprocessor; and an output compensation circuit electrically connected within the forward signal path between the coupler and the supplier side connector, the output compensation device being adjustable based on a level control output from the microprocessor, wherein the microprocessor comprises at least one control mode used to vary a slope control input and a level control input, wherein a first control mode varies at least one of the slope control input and the level control input based on a low channel level from each of at least one low frequency channel and a high channel level from each of at least one high frequency channel, wherein a second control mode varies at least one of the slope control input and the level control input based on an average of a plurality of the low channel levels, and wherein the first control mode differs at least one of the slope control input and the level control input at a faster rate than a second control mode.
