Electronic Communications: A Systems Approach, 1st edition

Chapter pedagogy helps students identify and learn key concepts.

• Each chapter includes a summary, review questions, and problems that review key concepts and help students see the "big picture."  

The emphasis on narrative structure, particularly in fundamentals chapters, offers a cohesive introduction to key concepts.

• Allows students to make connections between concepts at a conceptual level rather than memorizing a large number of seemingly unrelated facts. 

Reviews concepts covered in basic electronics courses, including nature of a sine wave, reactance and resonance, and classes of amplification.

• Acknowledges that there may be a significant lapse in time between the electronics fundamentals courses and the communications course.
• Gives instructors the opportunity to review some basics while placing the concepts in context, where their importance will become more apparent. 

Includes topics and end-of-chapter questions that help students prepare for the FCC General Radiotelephone Operator License exam.

• The FCC GROL is still valued in industry; many employers use it as a resume filter to screen applicants, and in some industries (particularly avionics) possession of the GROL is mandatory. 

Covers the latest in digital communications and digital signal processing.

• Most up-to-date treatment of enabling technologies behind latest-generation wireless systems, including 3G and 4G/LTE.
• Addresses the following topics: digital modulation, digital signal processing, finite-impulse response filters, spread spectrum, orthogonal frequency-division multiplexing, multiple-input/multiple-output configurations. 

Discusses topics not found in other communications texts intended for 2-year programs.

• Covers the following topics: SINAD (sensitivity) testing, squelch system operation, finite-impulse response filters and digital signal processing, the complex exponential and analytic signals, DSP modulation/demodulation, spread-spectrum techniques, wireless networks including 802.11n, Bluetooth and ZigBee, enhanced coverage of GSM and CDMA voice networks, coverage of two-way and trunked radio systems, software-defined radio, cavity filters/duplexers/combiners, impedance matching and network analysis (including S parameters), Maxwell's equations, and system link-budgeting and path-loss calculatiosns. 

Introduction to the concept of analytic frequency and the complex exponential.

• Describes the math behind many of the digital-signal processing implementations of digital modulation and demodulation that are now becoming mainstream implementations.
