Description


The voice or any other audible sound generated in the studio is very weak and cannot travel of its own to a long distance. It is amplified (processed) to make it strong enough to undertake the journey. Next, a carrier such as MW, SW, FM, Satellite communication, Internet etc. selected to take the voice to a long distance. On reaching the destination a radio receiver is used to off load the voice from carrier processed inside the radio receiver before it is fed to your ear. With the help of suitable analogy this chapter explains the characteristics and processing of audio sound, different carriers and the journey of voice from Microphone to Radio Receiver.

This lecture is useful for anyone to understand the technology of Radio Broadcasting even without having any technical background or knowledge. This may be very useful to media students to understand the basic concept of Radio Broadcasting.  




Who is the target audience?
  • In general anyone who wants to learn the basic concept of Radio Broadcasting.

TOP MANAGEMENT PROFESSIONAL

Brief Profile (June, 2010- Till date)

After superannuation from the government of India as the Engineer-in-Chief, Doordarshan, I remained active as a professional.

November 2013- October, 2016

Consultant (Technical & Programme), DUCR, University of Delhi.

Job profile includes in charge of Community Radio Station of University of Delhi popularly known as DUCR 90.4MHz. Also coordination with media colleges of Delhi University for production of Radio Programmes and Participation of students in management of Community Radio Station

Conducting training courses on Radio Broadcasting at various colleges of University of Delhi.

(June 2010 – November 2013),

Vice President, Asian Education Group, Film City, Noida.

In the capacity of Vice President during the last four years of being associated with media professionals, I discovered that there was a wide gap in the understanding of the technical aspect of the media technology that they were familiar with but half- baked knowledge made them a bit handicapped in giving out the best. I developed a few training modules which were simple and easy to understand and proved almost a boon during my teaching on the subject.

 This Education Group is conducting various graduate and post graduate level media courses in Cinema, Mass Communication, Electronic Media, Graphics and Animation, Multimedia Production and Digital Design etc. I achieved many landmarks including getting the multi-media coverage of the Queen’s Baton Relay by a three member team country wide  which culminated at the Jawaharlal Nehru stadium on October 3, 2010.  I was one of the privileged to have run with the Queen’s baton at Jaipur in Rajasthan.

I initiated the process of student participation as media partners to some of the country’s prestigious programs including Geosciences India 2011, a geosciences seminar and exhibition, under the aegis of ONGC, Broadcast Engineering Expo 2011, Sufi International Festival held at Ajmer and the recently concluded 27###sup/sup### Engineering Congress at Vigyan  Bhavan, held in December 2012.  This venture, appreciated by many media experts has been a major factor in uplifting the morale and confidence of the young students.

I am proud to say that my love for education in excellence steered me to get actively involved in the collaboration of Asian School of Communication with University of Central Lancashire, Preston, UK. After the successful validation and review by the UCLan team two courses in film production and International Journalism are running from its campus in Noida. I had the opportunity to visit the University at Preston including a purposeful visit to BBC Complex, Media City, Manchester.

Because of my keen interest in Indian cinema, I was made the festival director of the Global Film Festival for three successive years which saw a galaxy of Indian and foreign film personalities and gave an impetus to business generation. Various screening, workshops, master classes and exhibitions were conducted during the event. During my tenure in training institute of AIR and Doordarshan, I had the opportunity of imparting training to programme staff of AIR and Doordarshan on digital technology and satellite communication, application to new media, the knowledge of which I converted into making a series of modules which are beneficial to the media people.

I have been actively associated with different industry bodies including PHD Chamber of Commerce, ASSOCHAM, Indo-American Chamber of Commerce. There my work led me to organize seminars, film festivals through their entertainment and film committees.
