Digital Communication is a core area in M.Tech programs, focusing on transmitting information accurately and efficiently in digital form. This course covers the essential components of digital communication systems, including sources, encoders, modulators, channels, demodulators, and decoders, as well as the distinction between digital and analog systems. Key topics include:

• Signal Processing: Techniques such as sampling, quantization, and encoding enable the precise conversion and handling of analog signals in digital systems.

• Modulation Techniques: Understanding digital modulation methods like PSK, QAM, and FSK, which are vital for transmitting data over different channels.

• Error Detection and Correction: Introducing coding techniques, such as Hamming codes and cyclic redundancy checks, to detect and correct errors, ensuring data integrity.

• Noise and Interference: Analysis of factors affecting signal quality and strategies for minimizing their impact on communication.

• Modern Applications: Exploring applications in mobile communications, internet data transfer, satellite communication, and wireless networking.
