- For the following question, simply state your answer in the blank using only numbers (0-9). You do not need to show your work. If a base-10 number X requires a minimum of 10 bits to represent it in unsigned binary, what is the minimum number of bits necessary to represent X in hexadecimal?arrow_forwardSuppose we use the following code for compression. But, it could create ambiguities when decoding. Explain why. Also give an input text that cannot be decoded without any ambiguities after compressing it using the code. a : 101 b: 11 c: 10 d:0arrow_forwardTake the 127-bit binary BCH code with a 6-bit target distance and the 128-bit binary field extension F 128. How big is the code, and is there a minimum separation you can promise?arrow_forward
- Take into consideration the binary BCH code, which is 127 bits long and has a spacing of 6 bits, and use the binary field extension F128, which is 128 bits in size. How big is the code, and can you ensure a certain minimum space between entries?arrow_forwardwant genuine and correct answer dont copy from existingarrow_forwardQuestión Use Huffman coding to compress the letters in the following chart. What are the total bits of the compressed code? Code 000 001 010 011 100 Frequency 12 14 11 3 Character A Total Bits 36 В 42 C 33 6. 15 D E F N 101 110 13 39 1 3 a 177 bits b 151 bits 174 bits d 163 bitsarrow_forward
- If we use the 128-bit binary field extension F 128 to decode the 127-bit binary BCH code at a distance of 6, we get a total of 127 bits. How big is the code, and is there a guaranteed minimum separation?arrow_forwardPerform the specified operation using the given format Fill in table Operation Integer Binary Overflow? Answer Answer Format Representation (Y/N) (Binary) (Decimal) 6 bit signed 7*2 9 * -5 6 bit signed 16 *7 8 bit signed -12 *-5 8 bit signedarrow_forwardAssume that a system uses 10-bit floating-point representation based on the IEEE floating-point format, in which: . There is 1 sign bit. There are k= 6 exponent bits. The exponent bias is 31. . There are n= 3 fraction bits. ● Convert the decimal number -5.5 into the 10-bit IEEE floating point representation explained above. Write the final result in 10-bit binary format.
