A text/disk package for courses in advanced communications in twoand fouryear programs at vocationaltechnical schools and community colleges, assuming a previous course in AC theory. Covers basics such as frequency and bands, using the model of propagations and propagation paths, then proceeds to advanced topics including passive microwave components and communications applications. Includes chapter summaries, key equations, problems, and questions. Math is kept at the algebra or simple trigonometry level. The companion disk offers a tutorial on thermionic devices.
