The main objective of the study was to design and develop a local TV transmitter for Cavite State University-Main Campus. It specifically aimed to: construct a TV modulator that accepts composite and mono signal; design and construct a RF amplifier; construct transmitter and receiver antenna, and; determine the system cost. The design project was composed of a CCD camera and dynamic microphone as AN source, a TV transmitter and a transmitter antenna which were connected to the antenna port of the transmitter. The transmitter was composed of modulator circuit and amplifier circuit powered by a 12 V digital power supply. The TV transmitter was evaluated at the CvSU grandstand and quadrangle. A survey was used to determine the broadcast quality of the system in which fifteen (15) participants were invited. The quality of reception was evaluated at different distances and direction from the transmitter. T-test analysis was used to determine the relationship between open-field to grandstand broadcast and open-field to quadrangle broadcast. The constructed TV transmitter connected to a dipole antenna, transmitted signal in channel 14 with frequency band of 471-476 MHz. The transmission was affected by obstruction like trees and structures.
