<br/><br/> AGUSTIN, APRIL 0. and DAYANDAYAN, JOANNE MAURICE G. Design and Construction of a FM Transmitter for the School Bell System of Cavite State University. Undergraduate Design Project. Bachelor of Science in Electronics and Communications Engineering, Cavite State University, Indang, Cavite. April 2007: Engr. Edwin R. Arboleda. <br/>The main purpose of the design project was to design a centralized school bell system that can produce synchronized bell ring at scheduled time over a distance of 400 meters away from the base station which is the New Library Building. <br/>The design was composed of an FM transmitter, an omni-directional antenna connected to the antenna port of the transmitter, a computer wherein the Bell Commander software was installed and FM receivers such as radio, MP3/1\4134 player and 12-volt FM receiver. The device can transmit sound over 400-meter distance however the reception was greatly affected by obstructions like trees and buildings.<br/>
