The textbook " Communication Systems (Analog and Digital) " by Dr. Sanjay Sharma serves as a foundational roadmap for engineering students, detailing the evolution of how we transmit information. The following "story" outlines the logical progression of the concepts covered in his work. The Foundation: Signals and Systems
Alex, being an electronics enthusiast, had brought a two-way radio with him. It was an analog radio, which used continuous signals to transmit voice messages. As they began their trek, Alex explained to Ben how analog communication systems worked.
10. Engaging study tips
- Visualize signals in time and frequency domains.
- Build simple transmitter/receiver blocks in Python (NumPy + SciPy).
- Use SDR kits (e.g., inexpensive USB dongles) to hear/demo AM/FM and digital signals.
- Compare AM, FM, and QPSK on the same channel to feel trade-offs.
Comprehensive Coverage: With over 1,000 pages in its latest editions, it covers everything from the basics of amplitude modulation to advanced error control coding. Key Topics Explored
Practical Insights: The book frequently uses circuit diagrams and real-world examples to explain how theoretical modulation schemes are implemented in actual hardware. Core Content and Table of Contents
- Open the PDF to Chapter 2 (AM Modulation).
- Derive the time-domain equation for the AM wave.
- Solve 5 numerical problems on modulation index and power distribution.
Study Tips (for Students Using Sanjay Sharma’s Book)
- Master fundamentals: Fourier transforms, probability, and linear systems — they underpin modulation and noise analysis.
- Work problems: Derivations of SNR, BER, and sampling examples build intuition.
- Simulate: Use MATLAB, Python (NumPy/SciPy), or GNU Radio to model modulation, noise, and detection.
- Compare: Implement an analog chain and a digital chain for the same message to see practical differences.
The End
- Amplitude Modulation (AM): carrier amplitude carries information; simple but noise-sensitive.
- Frequency Modulation (FM): carrier frequency varies; better noise immunity for wideband signals.
- Phase Modulation (PM): phase carries info; used in many modern radio systems.
