Thursday, November 17, 2016 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! Tuesday, November 15, 2016 HW #12. Solutions to hw # 11. Review notes updated.
