Chapter2 Part8, Noise Characterization

🎓Noise Characterization in Communication Systems | SNR, Noise Figure, PSD & Autocorrelation
📘 Description:
In this lecture, we explore one of the most essential topics in communication systems — Noise Characterization. Understanding noise behavior is crucial for analyzing system performance and improving signal quality.
📺 What You’ll Learn:
🔹 Fundamentals of noise types: White noise and Narrowband noise
🔹 Definition and physical meaning of Signal-to-Noise Ratio (SNR)
🔹 Understanding Noise Figure (NF) and its role in receiver design
🔹 Power Spectral Density (PSD) and how it describes noise power distribution
🔹 Relationship between Autocorrelation Function and PSD
🔹 Practical examples and graphical explanations
🧠 Key Concepts Covered:
Additive noise models
System performance metrics (SNR and NF)
Noise analysis in baseband and passband systems
Frequency-domain characterization of random signals
📚 Ideal for:
Students, researchers, and engineers studying Digital Communication, RF Systems, or Signal Processing who want a clear and visual understanding of how noise affects system design and performance.
