What are the advantages of variable length coding?
Variable length coding (VLC) allows for more efficient data representation by using shorter codes for more frequent symbols.
Can you give me an example of how it works?
Sure! In Huffman coding, for instance, the most common characters are assigned shorter binary codes, reducing overall data size.
Are there any downsides to using variable length coding?
Yes, VLC can introduce complexity in encoding and decoding processes, and it may require more memory for the codebook.
How does it compare to fixed length coding?
Unlike fixed length coding, which uses the same number of bits for all symbols, VLC adapts the bit length based on symbol frequency, leading to better compression.
