CHAPTER ONE
1.1 INTRODUCTION
Electronic communication has gained
a holistic approach in the world technological growth. Apparently, no
modern electronic system is capable of fascinating the society without
an aspect of telecommunication. This trend is so progressive that most
remote control systems are designed with RF.
1.2 GENERAL DESCRIPTION OF THE PROJECT
The
above-mentioned development motivated me to embark on a project
research work on the design and construction of an Rf based remote
control electric lamp. This electronic system is designed with a
handheld remote control realized using frequency generator and modulator
coupled into a tuned class-C amplifier. The amplified signal is
radiated into the atmosphere through a tank circuit at a particular
frequency. The receiver is realized with a tuned radio frequency (TRF)
receiver coupled into a transistor static switch. These solid state
switches are used to clock a D-type flip-flop through a delay circuit.
The output of the flip-flop biases a driver circuitry realized using a
Darlington pair transistors which drives the relay to switch ON/OFF the
lamp connected to its normally open contact, whenever the remote is
pressed.
1.3 OBJECTIVES OF THE STUDY/PROJECT
One of the
objectives of this project is to design and implement an Rf based remote
control for electric lamp capable of switching ON/OFF of electric lamp
from a maximum distance of 200m at convenience.
It is also aimed at
exposing the graduating student to electronic system design using random
logic. It is also aimed at familiarizing the young engineers with
digital system design involving telecommunication systems. Another
objective of this project is to ground the young engineers in
engineering design which is indispensable in engineering professional
practice.

ABSRACT - [ Total Page(s): 1 ]This project work deals on the design and construction of an Rf based remote control for an electronic/electrical device say electric lamp with the aim of switching on/off of the lamp at discretion and from a distance. It also eliminates the inconveniences associated with manual switching of lamps. This electronic system is designed in two functional units; the transmitter and the receiver using radio frequency (RF) communication wave band. The transmitter is a hand-held remote control while ... Continue reading---
