Detailed explanation-1: -Huffman Coding is frequently used by conventional compression formats like PKZIP, GZIP, etc. For data transmission using fax and text, Huffman Coding is used because it reduces the size and improves the speed of transmission. More items •21-Nov-2022
Detailed explanation-2: -In audio compression scene, Huffman coding can be used to further encode quantized mantissa bits to lower the data rate or improve the sound quality at a fixed data rate by reallocating bit savings from Huffman coding back into the next block’s mantissas.
Detailed explanation-3: -The correct answer is option 1. Concept: Huffman coding is a lossless data compression algorithm. The idea is to assign variable-length codes to input characters, lengths of the assigned codes are based on the frequencies of corresponding characters.
