Description Comprehensive in scope and contemporary in coverage, thistext introduces basic electronic and data communicationsfundamentals, and explores their application in modern digital anddata communications systems. Students with previous knowledge inbasic electronic principles and fundamental calculus concepts willgain a complete understanding of the topics presented here.Tomasi's Advanced Electronic Communications Systems 6/e is the last10 chapters of this text. Rewritten material on satellites ?Includes their history; orbits; elevation categories; orbital patterns; and antenna look angles. Materials in the Fundamentals chapters on AM envelopes ?Produced by complex nonsinusoidal signals, Quadrature Amplitude Modulation, noise limiters and blankers, alternate signal-to-noise measurements, single-sideband suppressed carrier, frequency division multiplexing, double-sideband suppressed carrier, quadrature multiplexing, microstrip, and stripline. Material in the Advanced chapters ?On trellis encoding, CCITT modem recommendations, PCM line speed, extended superframe format, wavelength division multiplexing, Kepler's laws, Clark orbits, limits of visibility, Satellite Radio Navigation and Navstar GPS. Optical fiber communications has been moved from Chapter 20 to Chapter 11 ?Includes new sections on light sources, optical power, optical sources and link budget.
