Title: Innovations of Harvey J Ray

Introduction

Harvey J Ray is a notable inventor based in Winston Salem, NC (US). He has made significant contributions to the field of analog signal processing, holding 2 patents that showcase his innovative approach to technology.

Latest Patents

One of his latest patents is for an "Intermediate frequency (IF) sampling clock-to-clock auto-ranging." This invention operates directly on an analog signal in the IF band or higher, allowing it to track its gain range on a clock-to-clock basis. The result is a digital signal that maintains high resolution of the analog signal without clipping or loss of signal sensitivity. This is achieved by sampling an analog signal of sufficiently high frequency, enabling a peak detector to accurately determine the maximum signal level over at least one-half of a signal period. The signal gain is reset before the next sampling period, ensuring that the analog signal remains within the ADC's range.

Another significant patent is for a "High speed wide bandwidth digital peak detector." This device employs multiple peak detection stages that detect different sub-ranges of a full-scale analog signal range. By splitting the peak detector into multiple stages, the number of taps in each stage is reduced, which increases their bandwidth. The design minimizes the effects of offset errors in the individual stages while requiring gain stages with wider bandwidths to maintain amplitude resolution.
