Coding Theory: A Playful Introduction
5 hours ago
- The post introduces coding theory using a playful analogy of two children communicating with flashlights, starting with simple blinking and advancing to more efficient codes.
- Key concepts include base-1 coding, frequency analysis, Morse code, fixed-length ASCII, and optimal Huffman coding, each improving transmission speed.
- Huffman coding is optimal for compression but lacks error-correction, unlike ASCII which handles single-bit errors better.
- The article covers line coding schemes (NRZ, Manchester, 4B5B) for physical transmission, and extends to Unicode, channel coding, and cryptography.
- The final optimized system combines Huffman coding with 4B5B and NRZ-I encoding, achieving efficient and reliable communication.
