$$Binary\ Data\ Sequence - 10101010$$

Unipolar RZ

Unipolar RZ stands for Unipolar Return to Zero.
In this type of encoding, BIT– 0 is represented by a 0 Voltage line.
BIT – 1 is represented by Positive Voltages.
But, transition always occurs in the middle of the bit interval.
That means transition that starts at the POSITIVE side, makes the transition, and returns to the 0 Voltage side. (Z - Shape Pattern)

Uniolar RZ 10101010

Split Phase Manchester is nothing but Manchester encoding.
Manchester combines the logic of RZ and NRZ-L encoding techniques.
It is used by IEEE 802.5
BIT - 0 represents the transition that starts at the POSITIVE side, makes the transition, and returns to the NEGATIVE side. (Z - Shape Pattern)
BIT - 1 represents the transition that starts at the NEGATIVE side, makes the transition, and returns to the POSITIVE side. (Inverted Z - Shape Pattern)
