Electronic Communications: Principles and Systems
This book develops a solid understanding of the general principles that govern all communications systems. Topics include traditional analog communication techniques such as AM and FM, modern digital systems, radar, wireless, networking, consumer communications systems, and many other areas. Practical applications are stressed with an emphasis on signal processing at a systems level, in order to provide a better background for readers as technology advances and new integrated circuits become available.
Why Read This Book
You will gain a practical, systems-level understanding of how modern communications work — from classic AM/FM analog links to contemporary digital, wireless, and radar systems — with an emphasis on signal processing applications. The book blends conceptual clarity with engineering intuition and real-world examples so you can connect theory (filters, FFTs, spectral analysis, adaptive algorithms) to implementable designs.
Who Will Benefit
Intermediate engineers, graduate students, and practicing system designers who know basic signals and probability and want a broad, application-oriented treatment of communications, radar, and DSP in real systems.
Level: Intermediate — Prerequisites: Undergraduate calculus and linear algebra, basic signals & systems (time/frequency, convolution), introductory probability and random processes, and elementary circuit concepts; familiarity with MATLAB or similar tools is helpful.
Key Takeaways
- Explain the core principles of analog and digital modulation and demodulation, including AM, FM, PSK, QAM, and pulse modulation

How It Compares
Less mathematically dense than Proakis' Digital Communications and broader in systems and applications than Haykin's Communication Systems — it emphasizes practical DSP and system-design examples rather than exhaustive theoretical proofs.
