Title: Edwin L Froese: Innovator in Signal Processing and Video Communication

Introduction

Edwin L Froese is a notable inventor based in Surrey, Canada. He has made significant contributions to the fields of signal processing and video communication, holding a total of 2 patents. His innovative work has had a lasting impact on technology, particularly in the areas of clock recovery and signal classification.

Latest Patents

One of Froese's latest patents is titled "Clock recovery for video communication over ATM network." This invention presents a method for clock recovery from a fast packet switched asynchronous network. It involves maintaining an input counter at a sending device, which has a value dependent on an input clock. The value of this counter is periodically transmitted over the network to a receiving device. A local counter at the receiving device adjusts its frequency based on the average of error samples, ensuring accurate clock recovery, especially for MPEG2 video transmitted over ATM.

Another significant patent is the "Multi-frequency signal detector and classifier." This method and apparatus are designed to detect and classify signals that are combinations of constant-amplitude sinusoidal components, referred to as N-tones. The invention includes filtering to remove extraneous components and segmenting incoming signals into blocks of data samples. The frequency estimates are used to configure notch filters, which enhance classification performance while maintaining low computational complexity.
