6. Suppose we want an error-correcting code that will allow all single-bit errors to be corrected for memory words of length 10. a) How many parity bits are necessary? b) Assuming we are using the Hamming algorithm presented in this chapter to design our error-correcting code, find the code word to represent the 10-bit information word: 1001100110

5-Given that the ASCII code for A is 1000001, what is the ASCII code for J? Express the answer as 7 binary digits. 6- Suppose we are working with an error-correcting code that will allow all single-bit errors to be corrected for memory words of length 7. We have already calculated that we need 4 check bits, and the length of all code words will be 11. Code words are created according to the Hamming algorithm presented in the text....

In an even/odd parity error code a computer receives the following 4 bit word: 1101 Is this a valid word? Why or why not? If not, can it be corrected? If yes how if not why? At least how many Bit flip must separate code words If I want to correct (not just detect) 1 bit-flip errors?

Consider a (48, 36) block error correcting code used in the downlink control channel of a cellular system. This code can correct up to 5 bit errors in a block of 48 bits. If the 48 bit blocks are buffered until 10 blocks are collected and then they are interleaved and transmitted, what is the maximum error burst size that can be tolerated and still have correct reception of the data? What is the delay incurred in buffering the data...

Extra problem: Use the attached sheet to draw a 8- bit odd parity generator and a odd-parity checker for the 8 data bits and odd parity bit. Let the Error output be active-low (so that it goes low if there is an error and is high if there is no error) Parity Error-Detection System Using 74280s, design a complete parity generator/checking system. It is to be used in an 8-bit, even-parity computer configuration. Solution: Parity generator: Because the 74280 has...

Consider a binary communication channel transmitting coded words of n bits each. Assume that the probability of successful transmission of a single bit is p (and the probability of an error is q=1-p), and that the code is capable of correcting up to e (where e>= 0) errors. If we assume that the transmission of successive bits is independent, then what is the probability of successful word transmission? Hint: the word is successfully transmitted if there are e or fewer...

2. Design an even parity detection circuit. A parity bit is an error checking mechanism. Your circuit will count the number of 1's in a stream of bits. If the number of l's is even, the circuit turns on an output called y. Assume a single bit at each cycle - call the input x. Do not use an accumulator or counter. Design the even parity detection circuit using J-K flip-flops. Your answer must include: a. The state diagram. b....
