Calculating the performance of AM and FM receivers in the presence of noise.
Analog communication remains a foundational pillar of electrical and electronics engineering education. Despite the massive shift toward digital systems, understanding how continuous signals are modulated, transmitted, and received is crucial for designing modern wireless networks, RF circuits, and signal processing systems.

Evaluating the Signal-to-Noise Ratio (SNR) and Figure of Merit (FOM) for AM, DSB-SC, SSB, and FM receivers under noisy conditions. This includes explaining the threshold effect in FM. Unit V: Transmitters and Receivers
The textbook provides a structured approach to understanding how continuous-time signals are transmitted and received. It bridges theoretical mathematical frameworks with practical engineering applications, making it highly valuable for university curricula and competitive engineering examinations. Core Objectives
Here is the pdf version:
Angle modulation keeps amplitude constant while altering the phase or frequency, providing superior noise immunity.
Mathematical models to calculate the degradation of the Signal-to-Noise Ratio (SNR).
PM varies the phase of the carrier signal based on the message signal. It is closely related to FM and is often used in digital communication, though it is a fundamental analog concept. 3. Analog vs. Digital Signals
: Performance of various systems in the presence of thermal and shot noise. Amplitude Modulation varies the strength of the carrier
