UGC-NET | UGC NET CS 2016 Aug – III | Question 59

Which of the following is a source coding technique?
(A) Huffman coding
(B) Arithmetic coding
(C) Run-length coding
(D) DPCM


Answer: (D)

Explanation:

• DPCM is Differential pulse-code modulation which convert source analog into digital signal(i.e. source coding).
• Huffman coding is a lossless data compression algorithm.
• Arithmetic coding is a form of entropy encoding used in lossless data compression.
• Run-length encoding (RLE) is a very simple form of lossless data compression in which runs of data are stored as a single data value and count, rather than as the original run.

So, option (D) is correct.
