Error-free communication is a challenge, says expert

Communication is just like air, food and any other basic need for human being and there is no meaning for life without communication, NITK Surathkal Assistant Professor Dr H Prashanth Kumar said.

Delivering a talk on ‘Telecommunication and Information and Communication Technologies (ICTs) Drivers of innovation’ at a programme organised by The Institute of Engineers, The Institute of Valuers and Dakshina Kannada, Udupi and Kodagu district Engineers Association here on Tuesday, he said most inventions related communication were made during World Wars and during cold war and now scientists are just pushing them forward.

The invention of radio communication by Guglielmo Marconi in 1874 followed by invention of vacuum tube diode by John Ambrose Fleming unearthed new possibilities. Triode by Lee De Forest made way for many inventions. Edwin Howard Armstrong’s invention of FM and invention of transistor were milestones in the development of telecommunication.

Claude Shannon has been considered as father of digital information for his revolutionary ideas.
The integrated circuit was developed in 1959. In 1972, first microprocessor- 4004 was invented by Intel. The idea of telecommunication, the process of converting audio to electro magnetic signals was developed step-by-step.

Reducing bandwidth, higher and higher levels of modulation, reduction of noise, power efficiency, and reliable communication with zero error with error-free coding, compact and cheaper as possible are the challenges before modern communication, Dr H Prashanth Kumar said.
