Title: Kim S Guzzino: Innovator in Digital Phase Error Detection

Introduction

Kim S Guzzino is a notable inventor based in Los Angeles, CA. She has made significant contributions to the field of video technology, particularly in the development of digital phase error detection systems. Her innovative work has led to the creation of a patent that enhances the accuracy of color subcarrier signals in analog video.

Latest Patents

Kim S Guzzino holds a patent for a "Digital phase error detector for locking to color subcarrier of video." This invention involves a digital phase error detector that effectively locks onto a color subcarrier signal within an analog video signal. The system includes a digitizer that generates a first digital data stream from the analog video signal, along with filtering circuitry that eliminates DC offset. A mixer then combines the filtered data to produce a third digital data stream, which represents the sum and difference frequencies of the color subcarrier signal and a reference clock. An accumulator processes this data to determine the phase error, while a voltage-controlled oscillator generates the sample clock based on this error. This innovative approach significantly improves the reliability of video signal processing.
