摘要：The present invention relates to nonlinear signal processing, and, in particular, to adaptive nonlinear filtering of real-, complex-, and vector-valued signals utilizing analog Nonlinear Differential Limiters (NDLs), and to adaptive real-time signal conditioning, processing, analysis, quantification, comparison, and control. More generally, this invention relates to methods, processes and apparatus for real-time measuring and analysis of variables, and to generic measurement systems and processes. This invention also relates to methods and corresponding apparatus for measuring which extend to different applications and provide results other than instantaneous values of variables. The invention further relates to post-processing analysis of measured variables and to statistical analysis. The NDL-based filtering method and apparatus enable improvements in the overall properties of electronic devices including, but not limited to, improvements in performance, reduction in size, weight, cost, and power consumption, and, in particular for wireless devices, NDLs enable improvements in spectrum usage efficiency.

主权项：1. An apparatus comprising a filter transforming an input signal into an output filter signal, wherein said input signal is a physical signal and wherein said output filter signal is a physical signal, further comprising a nonlinear lowpass stage characterized by a bandwidth and transforming a nonlinear lowpass stage input signal into a nonlinear lowpass stage output signal, wherein said bandwidth is operable to depend on a magnitude of a difference between said nonlinear lowpass stage input signal and a feedback of said nonlinear lowpass stage output signal.
