Systems and methods for providing an output signal based at least in part upon an input signal and a clock signal in a manner in which jitter is avoided or diminished, including for example a digital-to-analog converter (DAC), are disclosed herein. In one example embodiment, such a system includes an output signal generating component, a first component having a first switch and a variable characteristic, and a plurality of second components each having a respective additional switch and a respective fixed characteristic. A value of the variable characteristic is set at least in part based upon input and clock signals so that, when the variable characteristic influences at least indirectly the generating of the output signal by the output signal generating component, the output signal attains a first level that at least indirectly depends upon a phase of the clock signal relative to the input signal.

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.
