that the data can be checked for integrity to correct for mistakes or
the clock on the receiver being out of phase.
NRZ coding and decoding
The NRZ encoding scheme is actually not a coding scheme at all.
It simply states that a ‘0’is transmitted as a ‘0’ and a ‘1’ is transmit-
ted as a ‘1’. It is only worth mentioning because a designer may see
the term NRZ and assume that a specific encoder or decoder was
required, whereas in fact this is not the case. It is also worth noting
that there are some significant disadvantages in using this simple
approach. The first disadvantage, especially when compared to the
Manchester coding scheme is that long sequences ...
