Title: **The Innovations of James Pressey: Pioneering Equalization Technology**

Introduction

James Pressey is an inventive force in the field of signal processing, recognized for his significant contribution to the development of advanced equalization technology. Residing in San Jose, California, he holds one patent that showcases his expertise and innovative approach to mitigating distortions in amplitude phase keyed signals.

Latest Patents

Pressey's notable patent is for a "Programmable Digital Linear and Nonlinear Transversal Equalizer." This advanced equalizer is designed to address both linear and nonlinear distortions, enhancing the quality of signals processed. By employing algorithms that focus on correcting received signals based on symbol transitions, the equalizer introduces programmable linear taps. These taps can utilize any available algorithm and can be programmed in a nonlinear manner using lookup tables, thereby acting as amplitude-dependent equalizers that process one symbol at a time. Each amplitude level is equipped with its own correction factor, achieved through amplitude-dependent coefficients. The mechanism of this equalizer allows for both linear and nonlinear equalization by storing predetermined values in lookup tables that can be dynamically adjusted via an external computer.
