Signals in Communication Engineering History
Consonni, Denise; Silva, Magno T. M.
IEEE Transactions on Education, v53 n4 p621-630 Nov 2010
This paper is a study of various electric signals, which have been employed throughout the history of communication engineering in its two main landmarks: the telegraph and the telephone. The signals are presented in their time and frequency domain representations. The historical order has been followed in the presentation: wired systems, spark gap wireless, continuous wave (CW) and amplitude modulation (AM), detection by rectification, and frequency modulation (FM). The analysis of these signals is meant to lead into a better understanding of the evolution of communication technology. The material presented in this work could be used to illustrate "Signals and Systems" and "Communication Systems" courses by taking advantage of its technical as well as historical contents. (Contains 19 figures and 1 table.)
