Title: Forrest A Edwards: Innovator in Digital Signal Processing
Introduction
Forrest A Edwards is a notable inventor based in Wilsonville, OR (US). He has made significant contributions to the field of digital signal processing, holding a total of 3 patents. His work focuses on improving the efficiency and effectiveness of data acquisition and display technologies.
Latest Patents
One of Edwards' latest patents is titled "Architecture providing increased information display for long acquisitions or constrained memory bandwidth." This invention presents a method and apparatus for rasterizing a digital sample stream by producing histograms for each of a plurality of time slices that form a display frame. The time slice histograms for at least one display frame are stored in a circular memory buffer and provided to a display raster for visualization. Notably, the first time slice displayed can be temporally associated with a trigger condition.
Another significant patent by Edwards is "Dithering apparatus to properly represent aliased signals for high speed signal sampling." This invention addresses the issue of aliasing in subsampled data by adding dither to the timing of the subsampling process. It effectively solves a speed problem caused by delays in modifying the A/D converter sampling clock. The invention recognizes that to maintain a high acquisition rate, samples should be randomly selected after demultiplexing the data into a wider and slower stream of samples, rather than attempting to modify the high-speed A/D converter sampling clock.
