... Pulse Amplitude Modulation is a form of signal modulation where the message information is encoded in the amplitude of a series of signal pulses. The output is a series of pulses, the amplitude of which vary in proportion to the modulating signal. The samples are taken at regular interval of time. ...

... modulation of 77%? 11. An AM signal has a 12-W carrier and 1.5 W in each sideband. What is the percentage of modulation? 13. The antenna current produced by an unmodulated carrier is 2.4 Ainto an antenna with a resistance of 75 ohm. When amplitude-modulated, the antenna current rises to 2.7 A. What ...

Signal Corps (United States Army)
The United States Army Signal Corps develops, tests, provides, and manages communications and information systems support for the command and control of combined arms forces. It was established in 1860, the brainchild of United States Army Major Albert J. Myer, and has had an important role from the American Civil War through to the current day. Over its history, it had the initial responsibility for a number of functions and new technologies that are currently managed by other organizations, including military intelligence, weather forecasting, and aviation.
