Book Description
The commonly accepted history of FM radio is one of the twentieth century’s iconic sagas of invention, heroism, and tragedy. Edwin Howard Armstrong created a system of wideband frequency-modulation radio in 1933. The Radio Corporation of America (RCA), convinced that Armstrong’s system threatened its AM empire, failed to develop the new technology and refused to pay Armstrong royalties. Armstrong sued the company at great personal cost. He died despondent, exhausted, and broke. But this account, according to Gary L. Frost, ignores the contributions of scores of other individuals who were involved in the decades-long struggle to realize the potential of FM radio. The first scholar to fully examine recently uncovered evidence from the Armstrong v. RCA lawsuit, Frost offers a thorough revision of the FM story. Frost’s balanced, contextualized approach provides a much-needed corrective to previous accounts. Navigating deftly through the details of a complicated story, he examines the motivations and interactions of the three communities most intimately involved in the development of the technology—Progressive-era amateur radio operators, RCA and Westinghouse engineers, and early FM broadcasters. In the process, Frost demonstrates the tension between competition and collaboration that goes hand in hand with the emergence and refinement of new technologies. Frost's study reconsiders both the social construction of FM radio and the process of technological evolution. Historians of technology, communication, and media will welcome this important reexamination of the canonic story of early FM radio.

Mathematics of the Discrete Fourier Transform (DFT)
Author: Julius O. Smith
Publisher: Julius Smith
ISBN: 097456074X
Category : Fourier transformations
Languages : en
Pages : 323
Book Description
"The DFT can be understood as a numerical approximation to the Fourier transform. However, the DFT has its own exact Fourier theory, and that is the focus of this book. The DFT is normally encountered as the Fast Fourier Transform (FFT)--a high-speed algorithm for computing the DFT. The FFT is used extensively in a wide range of digital signal processing applications, including spectrum analysis, high-speed convolution (linear filtering), filter banks, signal detection and estimation, system identification, audio compression (such as MPEG-II AAC), spectral modeling sound synthesis, and many others. In this book, certain topics in digital audio signal processing are introduced as example applications of the DFT"--Back cover

Sounds of Change
Author: Christopher H. Sterling
Publisher: Univ of North Carolina Press
ISBN: 0807877557
Category : Social Science
Languages : en
Pages : 336
Book Description
When it first appeared in the 1930s, FM radio was a technological marvel, providing better sound and nearly eliminating the static that plagued AM stations. It took another forty years, however, for FM's popularity to surpass that of AM. In Sounds of Change, Christopher Sterling and Michael Keith detail the history of FM, from its inception to its dominance (for now, at least) of the airwaves. Initially, FM's identity as a separate service was stifled, since most FM outlets were AM-owned and simply simulcast AM programming and advertising. A wartime hiatus followed by the rise of television precipitated the failure of hundreds of FM stations. As Sterling and Keith explain, the 1960s brought FCC regulations allowing stereo transmission and requiring FM programs to differ from those broadcast on co-owned AM stations. Forced nonduplication led some FM stations to branch out into experimental programming, which attracted the counterculture movement, minority groups, and noncommercial public and college radio. By 1979, mainstream commercial FM was finally reaching larger audiences than AM. The story of FM since 1980, the authors say, is the story of radio, especially in its many musical formats. But trouble looms. Sterling and Keith conclude by looking ahead to the age of digital radio--which includes satellite and internet stations as well as terrestrial stations--suggesting that FM's decline will be partly a result of self-inflicted wounds--bland programming, excessive advertising, and little variety.
