Signal interference reduction device and method

A system for transmitting and receiving spectra of signals having undesired signals and desired signals comprising:

• a transceiver system for at least one of receiving and transmitting signals;
• a TEE-junction coupled to said transceiver system and having first and second ports, said undesired and desired signals being separated at said TEE-junction;
• and
• an Interface system coupled to said second port;
• wherein said Interface system comprises:
• an In-line signal Interference reduction device coupled to said second port, and
• a signal input/output system coupled to said In-line signal interference reduction device;
• and
• wherein said In-line signal interference reduction device comprises:
• a filtering system,
• a first signal interference reduction device switch coupled to said second port,
• a second signal interference reduction device switch coupled to said signal input/output system, said filtering system coupled between said first and second signal interference reduction device switches, and
• a signal line coupled between said first and second signal interference reduction device switches, said switches being arranged to selectively decouple said In-line signal interference reduction device from the communication system.

An Off-line signal interference reduction device connected to a TEE-junction of a signal receiving system for shunting undesired signals comprising:

• a signal interference reduction device switch coupled to the TEE-junction for selectively engaging said Off-line signal interference reduction device;
• a main load coupled to a ground for dissipating said undesired signals;
• and
• a filtering system coupled between said signal interference reduction device switch and said main load.

An In-line signal interference reduction device coupled between a TEE-junction and a signal output system of a signal transmitting system for filtering desired signals comprising:

• a first signal interference reduction device switch having first and second terminals and coupled to the TEE-junction;
• a second signal interference reduction device switch having first and second terminals and coupled to the signal output system;
• a filtering system having a plurality of filtering channels connected between said first and second signal interference reduction device switches;
• and
• a signal line connected between said first terminals of said first and second signal interference reduction device switches, wherein said filtering system is connected between second terminals of said first and second signal interference reduction device switches, said first and second signal interference reduction device switches for selectively bypassing said filtering by coupling the TEE-junction and the signal output system through said signal line.

A method of reducing and eliminating undesired signals from desired signals from a signal source in signal transceiving systems comprising:

• separating said undesired and desired signals into a desired impedance path and an undesired impedance path;
• and
• dissipating said undesired signals in a Off-line signal interference reduction device, wherein the dissipating step comprises:
• selectively coupling the Off-line signal interference reduction device to the undesired impedance path;
• selectively passing the undesired signals to a load when the Off-line signal interference reduction device is coupled to the undesired impedance path;
• and
• dissipating the selectively passed undesired signals in a main load.
