An introduction to radio communication theory. Topics include Barkhausen criteria for oscillation, tuned amplifiers, rf amplifiers, transmission line effects, matching techniques using the Smith chart, spectral analysis using the Fourier series, signal/noise and noise figure calculations, non-linear mixing of rf signals, transmitter and receiver designs using amplitude, frequency and single-sideband techniques, superheterodyne principles, spectral analysis of FM systems using the Bessel function, modulators, detectors, stereo techniques, video principles, digital/data communication techniques, modems, networks, and fiber-optic systems. In the laboratory, students build, test, and measure the performance of communication circuits/systems using an assortment of popular devices such as the 3N211, 3080, 565, 1496 lumped-oscilloscope, spectrum analyzer, rf voltmeter, DMM, and service monitor. The compute is used to emulate, analyze, and collect data for communication circuits and systems. Through the use of Mathcad basic communication theorems are proven on the computer. Three class hours, five laboratory hours.
Prerequisite: ELT 201 with a grade of C- or better, or permission of department chairperson.
