IT1251 INFORMATION CODING TECHNIQUES 3 0 0 100
AIM:
To introduce the fundamental concepts of information theory: data compaction, data compression, data transmission, error detection and correction.
OBJECTIVES:
• To have a complete understanding of error–control coding.
• To understand encoding and decoding of digital data streams.
• To introduce methods for the generation of these codes and their decoding techniques.
• To have a detailed knowledge of compression and decompression techniques.
• To introduce the concepts of multimedia communication.
