Title: Ralph E. Nichols: Innovator in Signal Processing
Introduction
Ralph E. Nichols is a notable inventor based in Los Gatos, California. He has made significant contributions to the field of signal processing, particularly through his innovative patent that enhances the efficiency of digital signal transmission.
Latest Patents
Nichols holds a patent for a "Combined intraframe and interframe transform coding system." This invention describes an apparatus and method for signal processing that employs intraframe and interframe variable prediction transform coding. The technology allows images to be represented by sequential frames of two-dimensional arrays of digital signals. The digital signals are transformed to create transform coefficients for each frame. Predicted transform coefficients are generated using sets of variable prediction factors. These predicted coefficients are then compared with the actual transform coefficients for each frame to produce transform coefficient difference signals. The difference signals are processed to control their range of values. Furthermore, the processed difference signals are statistically coded, ensuring that more frequently occurring values are represented by shorter code lengths, while less frequently occurring values are represented by longer code lengths. The coded signals are subsequently stored in a buffer memory for transmission.
