NOISE IN TELECOM SYSTEMS

In this lecture, we explain the concept of noise in communication systems, its different types, sources, and effects on signal transmission. Understanding noise is essential for students and engineers in telecommunications, electronics, and signal processing, as it directly impacts the quality and reliability of communication channels.

Key Topics Covered:

• Definition of noise in communication systems
• Internal and external noise sources

Types of noise:

• Thermal, Shot, Flicker, and Impulse Noise
• Effects of noise on signal-to-noise ratio (SNR)
• Noise reduction and control techniques in communication systems
