Note on HW #12

For problem # 5 in HW # 12, NRZ stands for non-return-to-zero, which is the version of this codes that we talked about in class. RZ stands for return-to-zero, where the pulse does not cover the whole bit length (in time), just the first half of the bit length, and it 'returns' to zero for the second half.

In problems #6 and # 7, use the given sequence of bits just for part (a).

Enjoy the break!

Exam 2 results.

Exam 2 has been graded, and grades are available in Compass.

Exams will be handed back in class on Tuesday, November 15, and solutions are posted on the exam section of the course website. If when you receive your exam, and after looking at the posted solutions, you feel there was an inaccuracy in the grading of your exam, fill out an exam regrade request form (available in the exams part of the course website) and staple it to your exam BUT do not write on or alter in any way your original exam paper. Turn in such regrade requests to your instructor by the end of your lecture on Tuesday, November 29.

Statistics about the exam are as follows:
Average: 76.65
Median: 81.00
Standard Deviation: 17.35
Maximum Value: 98.00
Minimum Value: 23.00
