Question

Which statement is true about Huffman code?

(a) allow errors to be detected but not corrected

(b) allow only alphanumeric data to be corrected

(c) allow errors to be detected and corrected

(d) allow alphanumeric data to be compressed

I had been asked this question in a national level competition.

This key question is from FM Stereo Multiplexing in section Angle Modulation of Analog Communications

Answer 1

Right choice is (d) allow alphanumeric data to be compressed

Easy explanation: Huffman is generally used to convert fixed length codes into variable length codes. It results in lossless compression. It allows alphanumeric data to be compressed. It does not let alphanumeric data to be corrected or error to be detected and corrected.
