61. What is significance of D-frames in video coding
62. Which type of ARQ system introduces the transmission delay between the transmitter and receiver before the reception of frame at receiver for the purpose of error detection?
63. Which amount the following is capable of correcting any combination of three or fewer errors random errors in a block of 23 bits?
64. In dictionary techniques for data compaction, which approach of building dictionary is used for the prior knowledge of probability of the frequently occurring patterns?
65. In Repetition Code, how many information bit/s is/are present in addition to n-1 parity bits?
66. According to linearity property, the. . . . . . . . of two code words in a cyclic code is also a valid code word.
67. A linear Hamming code is used to map 4-bit messages to 7-bit codewords. The encoder mapping is linear. If the message 0001 is mapped to the codeword 0000111, and the message 0011 is mapped to the codeword 1100110, then the message 0010 is mapped to
68. The unit of average mutual information is
69. The method of converting a word to stream of bits is called as
70. A memoryless source emits n symbols each with a probability p. The entropy of the source as a function of n
