Title: John K Goatcher: Innovator in Radio Technology

Introduction

John K Goatcher is a notable inventor based in Harlow, GB. He has made significant contributions to the field of radio technology, holding 2 patents that showcase his innovative approach to radio signal processing.

Latest Patents

Goatcher's latest patents include a "Direct conversion radio receiver for FM signals." This invention features a demodulation system that produces an approximation to an analog output by measuring time intervals between successive zero crossings in the intermediate frequency (I.F.) or by filtering pulses produced at each zero crossing. The demodulator employs two signal pathways in quadrature phase relation, allowing for effective processing of analog information alongside digital signals. Another significant patent is the "Radio receiver with quadrature demodulation and digital processing." This multi-mode radio receiver divides the radio frequency input into two channels, mixing it with carrier wave frequencies. The quadrature shift in the mixing frequencies enables the filtering of baseband signals, which are then converted to digital form for further processing.
