Man Mohan Sondhi
Man Mohan Sondhi (18 December 1933 – 4 February 2018) was a prominent researcher in speech processing and signal processing who worked at Bell Laboratories during 1962–2001. He was famous for his research on echo cancellation. Born in Firozpur, Punjab, he was educated at Delhi University, Indian Institute of Science, and University of Wisconsin–Madison. As a specialist in speech science and signal processing, Sondhi recognized that the future of satellite communications would require developing a technology to cancel the 600 millisecond signal echo created by the delay of transmission. Sondhi and his collaborators at Bell Labs eventually created the echo canceller that made practical satellite transmissions possible. He received 5 patents. In 1998 he received the IEEE Eric E. Sumner award. References External links * http://www.ece.umd.edu/class/enee765.F2011/sondhi_mitra_1976.pdf {{DEFAULTSORT:Sondhi, Man Mohan 2018 deaths 1933 births Indian emigrants to ...

Bell Laboratories
Nokia Bell Labs, originally named Bell Telephone Laboratories (1925–1984), then AT&T Bell Laboratories (1984–1996) and Bell Labs Innovations (1996–2007), is an American industrial research and scientific development company owned by multinational company Nokia. With headquarters located in Murray Hill, New Jersey, the company operates several laboratories in the United States and around the world. Researchers working at Bell Laboratories are credited with the development of radio astronomy, the transistor, the laser, the photovoltaic cell, the charge-coupled device (CCD), information theory, the Unix operating system, and the programming languages B, C, C++, S, SNOBOL, AWK, AMPL, and others. Nine Nobel Prizes have been awarded for work completed at Bell Laboratories. Bell Labs had its origin in the complex corporate organization of the Bell System telephone conglomerate. In the late 19th century, the laboratory began as the Western Electric Engineering Department, l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
