Title: Todd S. Bowser: Innovator in Digital Signal Processing

Introduction

Todd S. Bowser is a notable inventor based in Itami, Japan. He has made significant contributions to the field of digital signal processing, holding a total of 3 patents. His work focuses on improving the reliability and efficiency of digital communication systems.

Latest Patents

One of his latest patents is the "Digital Signal Error Reduction Apparatus." This invention tracks and reduces both quickly changing errors and static errors in a digital signal, which are caused by time variant multipath distortion, co-channel interference, and other transmission path interferences, including nonlinear distortion. A transversal filter is implemented for filtering the digital signal, while an error detection device calculates the error of the digital signal. Additionally, a coefficient engine device receives the digital signal and the error, extracts the error, and updates a tap coefficient for the transversal filter to minimize the error.

Another significant patent is the "Forward Error Correcting Transmitter and Receiver." This invention prevents erroneous detection of synchronization in systems where synchronization of an interleaver circuit and a deinterleaver circuit is crucial. The synchronization is obtained from a synchronization detecting circuit of the Viterbi decoder. In this system, a Linear Feedback Shift Register (LFSR) is used as a row-direction address counter during writing, and an up/down counter serves as a column-direction address counter during reading in the interleaver circuit.
