Title: Alan C Thirlwall: Innovator in Signal Error Detection

Introduction

Alan C Thirlwall is a notable inventor based in Basingstoke, Hampshire, GB. He has made significant contributions to the field of digital television technology. His work primarily focuses on improving the accuracy of signal reproduction from video tape recorders.

Latest Patents

Thirlwall holds a patent for a signal error detecting apparatus. This invention is designed to achieve correct field framing on the reproduction of a digital television signal. The apparatus corrects errors in an input square-wave signal that alternates between first and second levels every four fields of the television signal. It includes first and second similar counters that count the input signal at different levels. Additionally, it features means to detect errors in the input signal and supply a signal to disable both counters when errors are detected. A clock pulse source provides a high-frequency clock pulse signal to the counters, while a bistable circuit is triggered by overflow signals from the counters to supply a corrected replica of the input signal.
