Analog Communication by V. Chandrasekar: A Definitive Guide for Electronics Engineers Analog Communication Systems

1. AM Power Calculation: A 400W carrier is modulated to a depth of 75%. Calculate the total power in the modulated wave. (Answer found in Chapter 2).
2. FM Deviation: An FM signal is given by s(t) = 10 cos[2π × 10^6 t + 5 sin(2π × 10^3 t)]. Calculate the modulation index and bandwidth using Carson’s rule. (Answer found in Chapter 5).
3. Noise Figure: The input SNR of a receiver is 40 dB. The noise figure is 6 dB. Calculate the output SNR. (Answer found in Chapter 7).

Frequency Modulation (FM): Changing the frequency of the carrier. Amplitude Modulation (AM) : In AM

Why V. Chandrasekhar’s Approach to Analog Communication Stands Out

There are dozens of textbooks on analog communication—from the exhaustive Proakis to the classic Taub and Schilling. So why does V. Chandrasekhar's book consistently appear at the top of student recommendations and search queries?

• Amplitude Modulation (AM): In AM, the amplitude of the carrier wave is varied in accordance with the information signal.
• Frequency Modulation (FM): In FM, the frequency of the carrier wave is varied in accordance with the information signal.
• Phase Modulation (PM): In PM, the phase of the carrier wave is varied in accordance with the information signal.
