Abstract

Frequency Modulated (FM) signal transmitter is a device for transmitting
Frequency Modulated signal over short range. The project is aimed at designing
independent transmitter-receiver system suitable for FUPRE academic
environment with extension to industrial, scientific and medical spheres. This
document outlines a straight forward and cost-effective design technique for
constructing a FM transmitter using simple electronic components like resistor,
capacitor, inductor etc. The transmitter was tuned to 101.0 MHZ at open space as
well as building, and trees while the FM receiver as well cellular FM radio receivers
were located at a radius of about 300m from the transmitting point. The system
was also tested at the lecture theater one auditorium close to the library, and
Tetfund one building (old Tetfund) at Federal University of Petroleum Resources,
Effurun, Delta State. A clear voice signal was received at these locations.
