Photo of Edwin Buzz Aldrin taken by Neil Armstrong in July 1969. Armstrong s reflection may be seen in Aldrin s visor. The suits worn by Armstrong and Aldrin during the Apollo 11 mission to the Moon appear to be massive. But because the mass of the Moon is only 1/81 that of Earth and the acceleration due to gravity is only 1/6 that on Earth, the weight of the suits on the Moon was only 1/6 of their weight on Earth. The mass of the suits, however, was identical in both locations. [Pg.73]

US electrical engineer Edwin Armstrong (1890-1954) develops frequency modulation radio broadcasting... [Pg.275]

Frequency modulation (Edwin H. Armstrong) Armstrong exploits the feet that, since there are no natural sources of frequency modulation (FM), FM broadcasts are static-free. [Pg.2057]

Frequency modulation (FM) is one of the most widely used modes of modulation. From applications in commercial broadcasting, television audio, cordless phones, to cellular and mobile communications, FM is indeed both a rehable and important form of modulation. The brainchild of Edwin H. Armstrong, FM was hrst demonstrated in December 1933 (Lewis, 1991, p. 256) as a solution to eliminate the static and noise problems that plagued AM communications. [Pg.1383]
