John R. Carson
John Renshaw Carson (June 28, 1886 – October 31, 1940) was an American transmission theorist for early communications systems. He invented single-sideband modulation and developed the Carson bandwidth rule for estimating frequency modulation (FM) bandwidth. In 2013 Carson was inducted into the Electronic Design Hall of Fame for his contributions to communications. Biography Carson was born in Pittsburgh, Pennsylvania, and together with his twin brother Joseph attended Princeton University, graduating in 1907 with a Bachelor of Science degree. John attended the Massachusetts Institute of Technology 1907–1908, before returning to Princeton to receive his electrical engineering degree in 1909 and a Master of Science degree in 1912. From 1912 to 1914 Carson was an instructor in Electrical Engineering and Physics at Princeton, but in 1913 was offered a position at American Telephone & Telegraph (AT&T), and in 1914 left the university. At AT&T, Carson was involved in early radio t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Carson Twins, From The Class Of 1907 Album
''The'' () is a grammatical Article (grammar), article in English language, English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the Most common words in English, most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant s ...

Bell System Technical Journal
The ''Bell Labs Technical Journal'' is the in-house scientific journal for scientists of Nokia Bell Labs, published yearly by the IEEE society. The managing editor is Charles Bahr. The journal was originally established as the ''Bell System Technical Journal'' (BSTJ) in New York by the American Telephone and Telegraph Company (AT&T) in 1922, published under this name until 1983, when the breakup of the Bell System placed various parts of the system into separate companies. The journal was devoted to the scientific fields and engineering disciplines practiced in the Bell System for improvements in the wide field of electrical communication. After the restructuring of Bell Labs in 1984, the journal was renamed to ''AT&T Bell Laboratories Technical Journal''. In 1985, it was published as the ''AT&T Technical Journal'' until 1996, when it was renamed to ''Bell Labs Technical Journal''.

Princeton University Library
Princeton University Library is the main library system of Princeton University. With holdings of more than 7 million books, 6 million microforms, and 48,000 linear feet of manuscripts, it is among the largest libraries in the world by number of volumes. The main headquarters of the university system is the Harvey S. Firestone Memorial Library building, named after tire magnate Harvey Firestone. Additionally, Princeton is part of the Research Collections and Preservation Consortium (ReCAP) along with Columbia Libraries, Harvard Library and New York Public Library. Firestone Library Firestone Library opened in 1948, as the first large American university library constructed after World War II. Roughly 1.5 million volumes were moved during the summer of 1948 from East Pyne Hall, which until then had served as the University's main library. The library building was expanded in 1971 and again in 1988 and currently has more than of bookshelves, making Firestone one of the largest ...

Laplace–Carson Transform
In mathematics, the Laplace–Carson transform, named after Pierre Simon Laplace and John Renshaw Carson, is an integral transform with significant applications in the field of physics and engineering, particularly in the field of railway engineering. Definition Let V(j,t) be a function and p a complex variable. The Laplace–Carson transform is defined as: : V^\ast(j,p) = p\int^_0 V(j,t) e^ \, dt The inverse Laplace–Carson transform is: : V(j,t) = \frac \int^_ e^ \frac \, dp where a_0 is a real-valued constant, i\infty refers to the imaginary axis, which indicates the integral is carried out along a straight line parallel to the imaginary axis lying to the right of all the singularities of the following expression: : e^\frac See also *Laplace transform In mathematics, the Laplace transform, named after its discoverer Pierre-Simon Laplace (), is an integral transform In mathematics, an integral transform maps a function from its original function space into anot ...

Elliott Cresson Medal
The Elliott Cresson Medal, also known as the Elliott Cresson Gold Medal, was the highest award given by the Franklin Institute. The award was established by Elliott Cresson, life member of the Franklin Institute, with $1,000 granted in 1848. The endowed award was to be "for some discovery in the Arts and Sciences, or for the invention or improvement of some useful machine, or for some new process or combination of materials in manufactures, or for ingenuity skill or perfection in workmanship." The medal was first awarded in 1875, 21 years after Cresson's death. The Franklin Institute continued awarding the medal on an occasional basis until 1998 when they reorganized their endowed awards under one umbrella, The Benjamin Franklin Awards. A total of 268 Elliott Cresson Medals were given out during the award's lifetime.
