Johnson D.H., Wise J.D. Fundamentals of electrical engineering

(1999)
From its beginnings in the late nineteenth century, electrical engineering has
blossomed from its focus on electrical circuits for power, telegraphy and tele-
telephony to a much broader range of disciplines. Still, the underlying themes are
relevant today: Power creation and transmission and information have run through
electrical engineering's century and a half life. This book concentrates on the latter
theme: the representation, manipulation, transmission, and reception of informa-
information by electrical means. This book describes what information is, how engineers
quantify information, and how electrical signals represent information.
