Analog Communication By V Chandrasekhar Pdf Fix

Introduction

1. Introduction to Analog Communication Systems: The book begins with an introduction to the basics of analog communication systems, including the types of signals, communication channels, and the concept of modulation.
2. Amplitude Modulation: The author explains the principles of amplitude modulation (AM), including the generation of AM waves, demodulation, and the analysis of AM systems.
3. Frequency Modulation: The book provides a detailed analysis of frequency modulation (FM), including the generation of FM waves, demodulation, and the analysis of FM systems.
4. Phase Modulation: The author discusses the principles of phase modulation (PM), including the generation of PM waves, demodulation, and the analysis of PM systems.
5. Analog Modulation Techniques: The book covers other analog modulation techniques, such as single-sideband modulation (SSB), vestigial sideband modulation (VSB), and quadrature amplitude modulation (QAM).
6. Noise and Interference: The author explains the effects of noise and interference on analog communication systems, including the types of noise, signal-to-noise ratio (SNR), and noise reduction techniques.
7. Communication Receivers: The book provides an overview of communication receivers, including the types of receivers, receiver components, and receiver performance.

Unit 3: Angle Modulation (FM & PM)

• Topics: Frequency Modulation vs. Phase Modulation, Narrowband FM (NBFM), Wideband FM (WBFM), noise in FM, and capture effect.
• Key Focus: Study the mathematical derivation of the FM wave and the concept of bandwidth (Carson’s Rule). V. Chandrasekhar explains the relationship between FM and PM very clearly here.

4. How to Use This Book Effectively

For University Exams:

1. Start with Definitions: The author provides clear definitions at the start of every chapter. Memorize these.
2. Follow the Derivations: Do not skip the steps. In exams, marks are awarded for steps (methodology), not just the final formula.
3. Solve the "Worked Examples": Exam questions are often modeled directly after the solved examples in the book.

The book follows a bottom-up approach, starting with basic modulation and moving toward advanced trends. Major topics include: Introduction
