Title: The Innovations of William J Anklam
Introduction
William J Anklam is a notable inventor based in Santa Rosa, CA (US). He has made significant contributions to the field of digital modulation and nonlinear transmission lines. With a total of 4 patents, Anklam's work showcases his expertise and innovative spirit.
Latest Patents
One of Anklam's latest patents is a digital baseband modulator adaptable to different modulation types. This invention features a flexible architecture that can be readily adapted to various digital modulation types. A symbol builder maps the input data to a series of modulation states corresponding to data symbols represented as state indexes. Additionally, a pair of digital filters accepts the state indexes generated by the symbol builder to provide both up-sampling and filtering functions. The digital filters utilize random access memory (RAM) to implement blocks of interpolating look-up multipliers, which can be configured between fast, normal, and long modes. The filtered output data from these digital filters is then provided to a resampler that converts it to an output sample rate corresponding to the sample rate of output DACs and analog low pass filters.
Another significant patent involves nonlinear transmission lines having noncommensurate varactor cells. This invention utilizes varactor diodes with noncommensurate parametric values within respective cells of a nonlinear transmission line. By selecting appropriate varactor cell parameters, the configuration of the nonlinear transmission line can be improved to address issues such as varactor turn-on and punch-through voltage limitations, soliton compression, and reflections from mismatched load and source impedances.
