Question

Depict the digit 1011001110 in 1) Manchester code and 2) bipolar RZ format

Answer 1

1) There are two ways to represent data in Manchester code:

> By G. E. Thomas (1949): 0-bit signal is low in the first half of the period and high in the second, and 1 is vice versa.

> By IEEE 802.3 and IEEE 802.4: 0 is high-low and 1 is low-high.

2) RZ format means Return-to-Zero, 1 is high signal (above zero), 0 is low (below zero), and each separate signal must return to zero.
