It uses Manchester coding at 212 kbit / s in the 13.56 MHz range.
2.
Manchester coding and modified frequency modulation have a bit rate equal to 1 / 2 the baud.
3.
On top of that ( or sometimes cleverly built into that ) is an encoding scheme, like manchester code.
4.
In the Manchester coding a transition from low to high indicates a one and a transition from high to low indicates a zero.
5.
The open standard-precision signal is generated with meander sequence ( Manchester code ), all generated using a single time / frequency oscillator.
6.
It is called NRZ because the signal does not return to zero at the middle of the bit, as instead happens in other line coding schemes, such as Manchester code.
7.
Manchester code always has a transition at the middle of each bit period and may ( depending on the information to be transmitted ) have a transition at the start of the period also.
8.
Manchester coding is widely used ( e . g ., in bandwidth to achieve the same data rate but may be less tolerant of frequency errors and jitter in the transmitter and receiver reference clocks.
9.
For a given data signaling rate, i . e ., bit rate, the NRZ code requires only half the baseband bandwidth required by the Manchester code ( the passband bandwidth is the same ).
10.
An exception from the above is some self-synchronizing line codes, for example Manchester coding and return-to-zero ( RTZ ) coding, where each bit is represented by two pulses ( signal states ), resulting in:
