Development of transmitter and receiver circuit using radio frequency for automatic announcement in LRT train / Mohd Nazrul Fazli Mohd Foudzi

This paper presents a solution for LRT train announcement problem by using wireless radio frequency transmitter and receiver circuit to energize the automatic announcement circuit. The circuit described generates ultrasonic sound of frequency between 315 Mhz to 350 Mhz. Transmitter which is placed a...
