Introduction

In digital communication , CellonicsTM offers a fundamental change to the way modem solutions have traditionally been designed and built. CellonicsTM technology introduces a simple and swift Carrier - Rate DecodingTM solution to the receiving and decoding of a modulated signal. It encodes and decodes signals at one symbol per cycle-a feature not found elsewhere. Its simplicity will obsolete the super heterodyne receiver design that has been in use since its invention by Major Edward Armstrong in 1918.In fact, according to one e ....etc

For the last 60 years, the way radio receivers are designed and built has undergone amazingly little change. Much of the current approach could be attributed to EH Armstrong, the oft -credited Father of FM, who invented the super heterodyne method in 1918.He further developed it into a complete FM commercial system in 1933 for use in public-radio broadcasting. Today, more than 98% of receivers in radios, television and mobile phones use this method.The subsystem used in the superhet design consists of radio-frequency (RF)amplifiers mixers ,phas ....etc
