Answer to Question #87660 in Electric Circuits for Shivam Nishad

Question

Depict the digital signal 1011001110 in (i) Manchester code and (ii) bipolar RZ
format.

Answer 1

Manchester coding options:

 by G.E. To Thomas: a logical zero is coded by a voltage drop from a low level to an upper level, and a logical unit is coded by a voltage drop from an upper level to a lower level.

IEEE 802.3 standard: a logical zero is encoded by a voltage drop from an upper level to a lower level, and a logical unit is encoded by a voltage drop from a low level to an upper level.

RZ code is a three-level, which provides a return to the zero level after the transmission of a significant interval.
