Latest Patents
James H. Buzzelli holds a patent for "RFI suppression by cascading nonlinear devices." This invention describes an enhanced nonlinear signal processor designed for RFI suppression. The processor utilizes either a biased null zone amplifier or a biased inverting limiter. By connecting two or more nonlinear interference processors in cascade, Buzzelli's invention introduces a deliberate tracking error. This error is selected to provide a small amount of relative interference rejection in each processor. The cumulative effect of each stage improves performance until a limit, determined by the input/output characteristics of each stage, is reached. The benefits of this discovery include increased dynamic range capability, simplification of gain control, and greater flexibility in hardware implementation options due to reduced sensitivity to RFI tracking error.
