Abstract

Frequency Modulated (FM) signal transmitter is a small device that can transmit Frequency Modulated signal over short range. [1] This document consists of most simple and economical technique for building a FM transmitter using basic electronic components like resistor, capacitor, inductor etc. The FM transmitter receives human voice signals though microphone. It further amplifies it, modulate it over carrier and finally transmit it. Assuming favorable conditions, output of transmitter can be received by anyone who tunes it in frequency of our transmitter. Here, I have described Circuit diagram, its working, components required, uses of various components in our circuit, its practical applicability. The design is simulated using NI Multisim and is further implemented on bread-board. This design is capable of transmitting signal for distance of radius 20m, tuned at 97.1 MHz One could clearly hear sound produced at microphone of transmitter.
