- Hamming-Code unplugged – Error detection and error correction
In this article, the Hamming code is first built with seven coins and without a computer and tested practically. You will learn how test bits can detect errors in a transferred bit sequence and determine the faulty position. The procedure is then programmed in a Jupyter notebook with Python. - Compressing Data with Smart (Part 2) – Converting Huffman Code in Python
In the first part, the example of COFFEE BREAK was shown how the Huffman algorithm creates a binary tree based on character frequencies and obtains space-saving, unambiguous codes from it. The basics are explained in detail in part 1 on ffritze.de. In this second part, the Huffman algorithm is implemented in Python and gradually traced in a Jupyter notebook. Thereby stands… Read more: Daten komprimieren mit Köpfchen (Teil 2) – Huffman-Code in Python umsetzen
