In many communication and networking systems, the signal transmitted on the
communication line uses a non-return-to-zero (NRZ) format. USB uses a specific
version referred to as non-return-to-zero inverted (NRZI). A circuit that converts
any message sequence of 0’s and 1’s to a sequence in the NRZI format is to be
designed.
The mapping for such a circuit is as follows:
• If the message bit is a 0, then the NRZI format message contains an
immediate change from 1 to 0, or 0 to 1, depending on the current NRZI
value.
• If the message bit is a 1, then the NRZI format message remains fixed at 0
or 1, depending on the current NRZI value.
For example,
Message: 10001110011010
NRZI message: 10100001000110
a. Find the Mealy model state diagram for the circuit.
b. Find the state table for the circuit and make an assignment
c. Find an implementation of the circuit using D flip-flops and logic
gates.
