two important aspects. The radio engineer is nearly always interested in transforming
the maximum amount of power from the transmitting to the receiving ends of the sys-
tem, whereas the electrical engineer is usually more interested in the transmission of
power between two points with a maximum of efficiency. Radio engineering practice
also differs from electrical engineering practice in the much greater range of frequen-
cies employed and in the utilization of certain electrical phenomena whose effects are
negligible at the comparatively low frequencies at which electric phenomena gener-
ated, distributed and utilized.
3. Modern radio communication rests on two fundamental bases (1) the analy-
sis, formulation, and manipulation of the intelligence to be conveyed, in a form suit-
able for transmission by radio means, and (2) the fundamentals of those branches
of physics (primarily electromagnetism) by which electromagnetic waves maybe pro-
duced, modulated in accordance with the intelligence to be transmitted, propagated
through space, and received at a distant point where the intelligence is extracted.
