Optical Reception Of Voice Signal Using Square Wave Frequency Modulation
Mohd Khairy Zahari, Abd Wahab · 2007
This project deals with the design of receiver for optical communication The type of modulation for receiver signals are square wave frequency modulation which has been differentially with sinusoidal modulation for others receiver. This project consists of several parts to extract the voice signal from square wave frequency to sine wave as output. The important parts of these projects are square to sine wave frequency converter, demultiplex or demodulator. The goal of this project is to improve the efficiency, quality and range of the communication system In order to build a good communication system, a good transceiver is necessary. Generally speaking, each transceiver is designed for its own purpose and for some specific applications. A transceiver works perfectly for one application may not suit for another situation. This project will establish a new reception model system of voice signal using square wave frequency modulation through optical sources like LED and Laser. This project will consist of 3 major parts. Firstly, analyze the suitable circuits and components to use for this project. Secondly, simulate the circuit to get the correct result The simulation and comparison will be in form of simulation using Mutisim® and Proteus®. Lastly, this report will reveal project implementation and development.
