Consider the Cyclic Redundancy Check (CRC) algorithm. Suppose that the 4-bit generator (G) is 1001, that the data payload (D) is 10011010 and that r=3. What are the CRC bits (R) associated with the data payload of D = 10011010, given that r=3?
Problem 8: Error Correction & Detection &
Problem 8: Error Correction & Detection (6 points) Assume a 10 by 6 array of data. How many bit errors can a 2D parity Checksum correct? How many can it detect? Compute data sent for a bit stream of 101011 with CRC using a generator 1010. What CRC bits are appended to the data. Randomly assume any bit to have been corrupted. Illustrate how the receiver can detect if the data was corrupted. Cite your reference. You are allowed...

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...

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....
