Abstract
A variable equalizer apparatus for forward and/or reverse equalizers in an amplifier. The system can include a structure to allow continuous contact of the signal flow as an equalizer is removed; jumpers with fixed resistors and associated capacitors and inductors to produce a variable range over many different values; and/or variable resistance potentiometers with fixed resistors and associated capacitors and inductors to produce a variable range over separate value equalizers.
Claims15
A cable communications equalizer device for outputting an equalized cable communications signal, the equalizer device comprising:
- an input for receiving a cable communications signal;
- a plurality of matched circuit components comprising:
- a variable resistance circuit component having a variable resistive value, and one or more fixed resistors operably connected to the one or more fixed resistors;
- a plurality of connector locations for receiving a repositionable selective jumper, wherein the variable resistive value is based on a selected position of the repositionable selective jumper;
- and
- an output for outputting the equalized cable communications signal.
A cable television amplifier comprising:
- at least one cable communications equalizer device comprising:
- an input for receiving a cable communications signal;
- a plurality of matched circuit components comprising:
- a variable resistance circuit component having a variable resistive value, and one or more fixed resistors operably connected to the one or more fixed resistors;
- a plurality of connector locations for receiving a repositionable selective jumper, wherein the variable resistive value is based on a selected position of the repositionable selective jumper;
