- When bit stuffing is used, is it possible for the loss, insertion, or modification of a single bit to cause an error not detected by the checksum? If not, why not? If so, how? Does the checksum length play a role here? Please elaborate the Answer ?Explain the term masking. How is it useful for data representation? Explain the concept using an example For a floating-point format with a k -bit exponent and an n -bit fraction, give a formula for the smallest positive integer that cannot be represented exactly (because it would require an n + 1 –bit fraction to be exact).Manchester encoding guarantees frequent clock synchronization by changing signal values. What is the maximum number of bits which may be encoded without a signal change? (Note: The way this question has been asked. you are not to include the bit which includes a signal change in your count)
- As the error-detection and correction capability of a code increases, we would expect in general the overhead bits to protect a group of data bits to decrease remain the same increaseIf the floating-point number representation on a certain system has a sign bit, a 3-bit exponent and a 4-bit significand: What is the largest positive and the smallest positive number that can be stored on this system if the storage is normalized? (Assume no bits are implied, there is no biasing, exponents use two's complement notation, and exponents of all zeros and all ones are allowed.) What bias should be used in the exponent if we prefer all exponents to be non-negative? Why would you choose this bias?In Cyclic redundancy check (CRC), the dataword is 5 bits and the codeword is 8 bits.[15 marks]i.How many 0s need to be added to the dataword to make the dividend?ii.What is the size of the remainder?iii.What is the size of the divisor?
- Using the Hamming code given in classfor 8 bit data words, determine whether there is an error, and if so, in which bit, for each of the following words fetched from memory: A.0010 0011 0010 B.0110 0011 1010What is the relationship between the number of redundant bits required for code and the number of data bits?An 8-bit byte with binary value 10101111 is to be encoded using an even-parity Hamming code. What is the binary value after encoding? ANS: The encoded value is 101001001111 Why is this answer longer from binary value? Please solve this question with details. Please explain why you use that method.
- Using the Hamming code given in class for 8 bit data words, determine whether there is an error, and if so, in which bit, for each of the following words fetched from memory: 0010 0011 0010Two Dimensional Parity can detect as well as correct one or more bit errors. If a one or more bit error takes place then the receiver will receive the message with the changed parity bit. It indicates that some error has taken place which means the error is detected. According to this calculation, identify the error bit by stating the column and row number. Assume even parity was implemented. 0 1 0 1 11 0 0 0 11 101 1 1 10 0 1 1 0 1 11 0 10 10 0 0 0 11 1 1 0 0 1 1 0 1 0|0Take into consideration the binary BCH code, which is 127 bits long and has a distance of 6 bits intended for it, and use the binary field extension F 128, which is 128 bits in size. How big is the code, and can you guarantee a certain minimum distance between entries?
