Abstract:
A balancing circuit for balancing return path transmissions in a coaxial cable communication system comprising:a plurality of series coupled capacitors coupled between respective input and output ends;a first inductor having a first terminal coupled to said input end, and having a second terminal;a first capacitor having a first terminal coupled to the second terminal of said first inductor, and having a second terminal coupled to ground;a second inductor having a first terminal coupled to said output end, and having a second terminal;a second capacitor having a first terminal coupled to the second terminal of said second inductor, and having a second terminal coupled to ground;a first resistor having a first terminal coupled to the first terminal of said first capacitor, and having a second terminal coupled to ground; anda second resistor having a first terminal coupled to the first terminal of said second capacitor, and having a second terminal coupled to ground, wherein the balancing circuit substantially equalizes signal attenuation levels within a given return path frequency range.
