Question 1: Design the Hamming error correcting code for a nibble, Derive the G and E matrix and list all the possible values of S and what they mean. Question 2: Use the results from question 1 and show examples of what happens when a nibble is received without errors and when a nibble is received with an error. Question 3: How can the Hamming error correcting code be improved? What are the improvement(s) and implications?

Answer #1

E means message = 1010 ( as per solved above)

P1=S1= =1: positions checked for even parity positions 1,3,5,7

P2= S2= 0 : positions checked for even parity positions 2,3,6,7

P3= S3= 1 : positions checked for even parity positions 4,5,6,7

(s1s2 s3) =( 1 0 1)

Matrix

G= [ E1G ]

E2G

E3G

E4G

Question 1 - Debugging Java Problem Description: Commonly attributed to Grace Hopper in the 1940s (when a moth found in a computer relay was fouling outputs), debugging is the practice of removing errors from code. It is a systematic procedure of examining the output, drawing a hypothesis for the cause of the error, then either implementing a correction or otherwise validating or falsifying the original error hypothesis. We are hunting and correcting errors in a controlled, systematic fashion. Most IDEs...

Experiment 1: Billy Rae Thompson wanted to test a new "singalong" method to teach math to sixth graders (e.g., "All the integers, are natural numbers" to the tune of "Call me Maybe"). He used the singalong method in his first period class. His sixth period students continued solving math problems with the old method. At the end of the term, Mr. Rogers found that the first period class scored significantly lower than the sixth period class on a mathematics achievement...
