520			_a"Intended Audience This text is intended for students in two, three-, and four-year programs in electronics technology and electronics engineering technology. It includes both traditional analog communication amplitude and frequency modulation and their variations-and modern developments in digital and data communications and networks. Radio and optical transmission systems are also given extensive coverage. There is enough material in this text for a four-course sequence. For example, a basic analog communication course could include chapters 1 through 6. Chapters 7 through 13 could comprise a basic digital communication course. Chapters 14 through 17 could be the basis of a course in radio-frequency fundamentals. The chapters from 19 through 25 would be suitable for a senior-level course in the application of theory to actual systems. Of course the material can be divided in many different ways to suit the individual school. Prerequisites This text assumes a basic knowledge of analog and digital electronics. It is expected that students may need to be reminded of the ways in which high-frequency circuits differ from those operating at audio frequencies, so these differences are reviewed. Class C and other tuned amplifiers are also explained because students may not have covered them in previous courses. The text does not assume that students are familiar with mixing and modulation or with techniques for making measurements at radio frequencies, so these topics are covered in the text. Phase-locked loops are explained at a basic level, and no prior knowledge of these devices is assumed. Frequency-domain analysis is essential in any book of this type, and Fourier analysis is introduced in the text. No prior knowledge is assumed It is assumed that the student's mathematical background includes algebra and basic trigonometry. Calculus is not required, but knowledge of logarithms and decibels is assumed in the text; these topics are reviewed in an appendix." —Preface
