Title: Innovations by John Kaufmann: A Pioneer in Signal Processing

Introduction

John Kaufmann, an inventive mind based in Palo Alto, CA, has made notable contributions to the field of signal processing with a total of three patents to his name. His groundbreaking work primarily focuses on enhancing the functionality of filters used in communication systems.

Latest Patents

Kaufmann's latest patent, "Signal conditioner with symbol addressed lookup table producing values," describes a signal conditioner featuring several embodiments of transversal (FIR) filters. These filters utilize symbol addressed multiplier lookup tables, generating predistorted waveforms within the transversal filter to compensate for the effects of nonlinear amplifiers and intersymbol interference. The invention simplifies the implementation of FIR filters aimed at providing a transversal filter function for symbolic waveforms. Traditionally, the complexity in representing digital samples of waveforms can be significantly reduced through this innovation. Additionally, this patent cleverly combines waveform generation with symbol addressed lookup tables, effectively mitigating intersymbol interference and transmitter nonlinearities.

Another of Kaufmann's innovations is the "Programmable PCM/TDM demultiplexer." This invention integrates a Frame Alignment Logic (FAL) function unit, which is controlled by a Programmable Frame Alignment Controller (PFAC). It also includes a Decommutation and dejustification (DEC) function unit, each managed by a Programmable Decommutator Sequencer (PDS) and its controller. These sophisticated units enhance the performance of demultiplexing functions in communication systems.
