Abstract
A soliton rejection filter circuit is provided, for use in RF signal procing, for isolating a low level signal in the presence of stronger nearby interfering signals and detecting its modulation over a wide communication bandwidth centered at a relatively low RF frequency. The soliton filter circuit includes a nonlinear transmission line and a filter circuit.
Claims4
A soliton interference rejection circuit comprising:
- two input terminals both simultaneously receiving an intended signal and an interferer signal;
- a nonlinear transmission line for producing soliton waves and for predetermining a soliton region where the soliton waves occur, the nonlinear transmission line being coupled to the two input terminals;
- and
- a filter circuit for removing the undesired interferer signal, the filter circuit being coupled to the nonlinear transmission line at the soliton region.
