Title: Michael A Sowell: Innovator in Delta Modulation Technology

Introduction

Michael A Sowell is a notable inventor based in Chandler, AZ (US). He has made significant contributions to the field of delta modulation technology, holding 2 patents that showcase his innovative approach to signal processing.

Latest Patents

One of his latest patents is the "Software Controlled Adaptive Delta Modulator." This invention discloses a delta modulator that automatically adjusts the slewing rate. In the absence of a transition in the output data, a parameter used for the integrator of the delta modulator is increased. When the comparator indicates that the feedback signal has overshot the input signal, the parameter is decreased or reversed until the two signals are approximately equal, as signaled by a 50% duty cycle. Another significant patent is the "Digitally Controlled Adaptive Slew Rate Delta Modulator." Similar to the previous invention, this delta modulator adjusts the slewing rate automatically. The current used for the integrator is increased in the absence of a transition, and when the feedback signal overshoots the input signal, the current is decreased or reversed until the signals are approximately equal.
