Department of Electronics & Communication organised an industrial visit to Akashbhavan, Kadri, Mangaluru for the students of second year as an activity supporting the course Analog Communication Engineering. This industrial visit was organized by Ms. Padmini Bhat, coordinated by Ms. Shama B. N, and accompanied by Ms. Vijayalaxmi.
All India Radio (AIR) is India’s national public radio broadcaster, operates under Prasar Bharati, India’s largest public broadcasting agency. The station is equipped with state-of-the-art analog and digital transmission systems, making it a live example of practical analog communication in action This visit was a significant opportunity to bridge the gap between academic learning and real time application.
The visit began with a talk by Mr Chandrashekar Shetty, Senior Engineer who shared his extensive knowledge about the vital role played by AIR in dissiminating the information to public. During the visit to the All India Radio Station, students were introduced AM and FM transmission techniques which explained about amplitude modulation (AM) and frequency modulation (FM), including carrier generation and audio signal modulation. Also demonstrated high-power transmitters and associated antenna systems used for broadcasting over long distances.
Students witnessed the insights of how audio signals are transferred from the recording studio to the transmission tower. Explanation of Audio Processing Units provide the understanding of pre-emphasis, de-emphasis, and signal equalization techniques. Technical officials explained the overview of monitoring equipment used for maintaining signal quality and adhering to broadcast standards. The technical staff also discussed the historical evolution of analog broadcasting, the transition to digital platforms, and the importance of frequency management and licensing in communication systems.
The industrial visit to AIR Station proved to be a highly enriching and educational experience. It not only reinforced classroom learning but also motivated students to explore careers in the field of broadcasting and communication engineering.
