2 cards from this section. Quick, good the night before a test.
What is the main purpose of Huffman coding?
Think about how encoding methods can affect data size.
Define what a prefix code is.
Consider why it is important for decoding clarity.
What does Huffman coding aim to achieve?
Consider how encoding affects transmission efficiency.
True or False: In Huffman coding, each code can serve as a prefix for another code.
Remember why unique decoding is crucial.
Given the character frequencies: A=0.5, B=0.25, C=0.15, D=0.1, construct a Huffman tree and derive the binary codes for each character.
Remember to always combine the least frequent characters.
Explain how changing the frequency of characters affects the average bits per letter in a Huffman encoding scheme.
Consider how the principle of shorter codes for frequent letters applies.
