Background
Posner was born on August 10, 1933, in Brooklyn, and graduated from Stuyvesant High School in 1950. At Stuyvesant, one of his close friends was mathematician Paul Cohen.

There are many valuable and useful books on electrical communication (References 1-5 are some examples), but they have certain disadvantages for the beginner. The more advanced books present some things in a basic way, but they are very narrow for an introduction to communica tion. The introductory books are broader but still narrow by our stan dards. Further, they often pick things out of thin air rather than derive them. This book is aimed at giving the beginner a basic understanding of a wide range of topics which are essential in communication systems. These include antennas and transmission, thermal noise and its consequences, Fourier transforms, modulation and noise, sampling and pulse code modulation, autocorrelation and power spectrum, optimum filtering, gauss ian noise and errors in digital transmission, data transmission, limits on data rate including information theory and quantum limits, and source encoding. We have not included communications traffic, switching, and multiplexing, nor protocols for digital and computer communications. For these, Reference 6 is excellent. In general, our book does not discuss the circuits used for communication or the physics of radio propagation. We assume that these will be taught in specialized courses, but such courses are not prerequisites for this one. Chapter 1 introduces the transmission formula or antenna equation and antenna directivity. Only a very basic sophomore physics knowledge of electromagnetic theory is assumed. The radar equation is also treated.

Posner was born on August 10, 1933, in Brooklyn, and graduated from Stuyvesant High School in 1950. At Stuyvesant, one of his close friends was mathematician Paul Cohen.
He took only two years to complete his undergraduate studies in physics at the University of Chicago, graduating in 1952, and he then switched to mathematics for a master"s degree in 1953 and a Doctor of Philosophy in 1957.
While a graduate student, he also visited Bell Labs, and later claimed that he had been assigned to the desk there that had formerly been Harry Nyquist"son His doctoral thesis, supervised by Irving Kaplansky, was on the subject of ring theory and entitled Differentiably Simple Rings. At only 26 pages long, it held the record for the shortest doctoral thesis at the university.
After finishing his studies, he became a mathematics instructor at the University of Wisconsin and then an assistant professor of mathematics at Harvey Mudd College.
In 1961, Solomon West. Golomb hired him to lead the Information Processing Group at Jet Propulsion Laboratory. He led the group for 10 years and then, after a sequence of positions in higher management, he became chief technologist in Jet Propulsion Laboratory" General’ s Office of Telecommunications and Data Acquisition in 1982. He also held lecturer and visiting faculty positions in the applied mathematics and electrical engineering departments of the California Institute of Technology beginning in 1970.
He died after being hit by a truck while bicycling to work on June 15, 1993.
