1.NRZ I---

In telecommunication, a non-return-to-zero (NRZ) line code is a binary code in which "1s" are represented by one significant condition (usually a positive voltage) and "0s" are represented by some other significant condition (usually a negative voltage), with no other neutral or rest condition.

The NRZ I code of 011101101-----

0 1 1 1 0 1 1 0 1

mancestor coding-----

In telecommunication, Manchester code (also known as Phase Encoding, or PE) is a line code in which the encoding of each data bit has at least one transition and occupies ...
